       Understanding Laser Power and Energy
            Measurement Technologies
Foreword
Laser Point manufactures a complete range of state-of-the-art detector heads and monitors for
measurement of powers and energies of all lasers, from UV to the Far Infrared, in any application
within the industrial, medical or scientific fields.
Those detectors can mate to a whole family of precise and sophisticated monitors and meters
which include intelligent detector connection, analog and digital displays, analog and digital outputs
and application software .
Technology
Laser Point has put a lot of technology into the design of its heads.
A head is substantially made of a sensor disk and a housing with its heat sink or cooling devices. Each of these
assemblies are critical in view of the final performance of the system. Parameters like thermal stability, linearity, spatial
uniformity, heat dissipation are calculated by our Engineers and extensive thermal SW modelling (Thermal Analysis
System-TAS) is made to verify the behaviour and achieve the highest reliability even in those demanding environments
represented by high power lasers .
Absorbing coatings are another important chapter in the head design. They have to face high damage thresholds as a
function of the wavelength of use. LaserPoint has adopted various types of radiation absorbers, simulated by TAS and
deposited with the latest technologies (e.g. plasma) under the tightest specifications, to resist extreme thermal and
mechanical stresses.




                            10W-Sensor Disk                                    5KW-Cronos

Selecting a measurement system
The selection of a measurement set-up is, in general, an easy task. On the following pages you will find detailed
specifications for each of Laser Point’s heads and readout units that will help you in defining what is needed for your
application.
Of course there may be exceptions or special requirements: in those cases feel free to apply to our Engineers or
Distributors for complete technical support.
The first step in the selection is to look for a detector capable to match the power and/or energy specifications of the
laser; the next is to select a monitor that meets with user’s requirements, e.g. having a graphical display or an
application SW.

The entire working range has to be determined. The Power or Energy Resolution represent the minimum values which
can be detected with an optimum signal-to-noise ratio, while the Max Continuous Power or the Max Energy are the
maximum values at which the detector can safely work with no time limits. Nevertheless, should there be the necessity
to make measurements at higher powers or energies, this can be done for a limited period of time, up to 1.5 times the
max value (Intermittent Power Use).

Verify if Absorber Type, Wavelength Range and Max Average Power/ Energy Density specs are consistent with the
laser type; furthermore when working with short pulses (as is the case of various medical lasers or Q-switched Nd-Yags)
and want to measure average power, attention has to be given to the Max. Peak Power Density. LaserPoint has a wide
selection of products whose absorbers, like those working on the volume absorption principle, offer the highest
damage resistance to short pulses.

The Cooling type is another feature to look at; if bringing water to the head is a problem, there are convection or fan
cooled detectors which can be used. For example, our A-600 head can work at 600W continuously or dissipate 800W
for a short period, but that’s really a technological goal of LaserPoint thermal design. For higher powers water cooling is
necessary.

Finally, LaserPoint’s versatile and best-buy monitor    PLUS or industry favorite LPM are the user friendly meters to
be associated with any of LaserPoint detectors.

                                                                                       web: www. laserpoint.it
Operating Principles of Thermal Heads
This section describes the very basics on which LaserPoint’s sensors and detectors work .It is
intended to introduce the laser user with terminology and principles which are repeatedly
mentioned in the catalog and can be used as a help in choosing the power/ energy instrumentation.

Thermal methods of measuring power and energy are those in which radiant energy is absorbed and converted into
heat, thus creating a temperature rise in the absorber. The absorbed energy can then be measured by monitoring a
temperature gradient between the hot area ( where the laser strikes) and a cool area (where the generated heat is
dissipated). This measurement can be done by means of thermocouples arrays (thermopile). The temperature
difference will generate a voltage at the end of each single thermocouple, so if the array is duly distributed, the resulting
total voltage will be proportional to the incident power or energy.

As the generated voltage depends on the temperature difference between the hot and the cold areas it results that
there is no influence of ambient temperature on the measurement.

Thermal detectors exhibit an intrinsic high degree of linear response at the increase of power levels (linearity); a
compensation for the minor drops in linearity occurring at the working temperature extremes are made with the use of
thermistors. Linearity of LaserPoint’s detectors, thanks to their optimised thermal design, is excellent: as an example,
for the W-1000 head as measured by PTB (Physikalisch-Technische Bundesanstalt) in the range between 60-1000W,
it remains within +/-1 % without compensation.

The generated heat all flows through the
thermocouples, whether they deposited on circles
(radial thermopiles) or linearly, with the hot and cold
areas facing each other (axial thermopiles). Since the
total signal is given by the sum of contributions from
all thermocouples, the result is the independence from
laser beam size and position

The response time is determined the thermal
resistances, the thermal capacities and, mostly, by the
geometrical sizes of the sensor disks. The intrinsic
response times of detectors is significantly reduced
by appropriate acceleration algorithms in LaserPoint’s
monitors. A detector like LaserPoint’s A-300, which
has an intrinsic response time of 11 sec due to its very
large area, displays the final power value only after 3.5
sec.

To dissipate the generated heat a thermal sensor
must be placed within a housing which, depending on
the amount of heat to be driven away, can work by
simple convection, have electrical low voltage fans or
be water cooled. So as the thermal contact between sensor and housing is very critical since it might generate
overheating of the sensor and instabilities in the signals, the final shape and dimensions of the heads must be carefully
designed to maintain the sensor temperature within its working limits. An example of excellent thermal dimensioning is
LaserPoint’s W-6000 head, which can safely work up to 9KW.

                                                                                       web: www. laserpoint.it
A New Approach on Thermal Heads Design: the FIT Product Lines
In some sections within this catalog Fit detectors are mentioned. These
heads are available for different applications : as laserprobes, where a
full product line bears the same Fit name and as detector heads for the
PLUS monitor or the Laser Process Monitor LPM.
Fit, acronym for Fast Integrative Thermopile, is a measurement
technique of temperature dynamics throughout thermopile sensors
developed by LaserPoint (Patented.) which led to a novel family of
detectors. A dedicated algorithm converts sensors data into fast ,
repeatable and precise readings.
Fit detectors have provided a series of breakthroughs in laser
measurement: infact, while keeping the advantages of thermopile
detector heads (e.g. their use at any wavelength or their fast response
times) , Fits need no water cooling even when working at several
kilowatts, while still allow repeated measurements. As a laserprobe, no
other similar instrument on the market has ever been so repeatable and
precise, before .
Fit detectors can be used in all those cases where availability of
cooling water is an issue or when space is limited but ,above all, where
long term laser power measurements are not necessary while quick,
occasional checks are enough.
In these cases the Fit detectors, either associated with a Plus monitor,  FIT-6000-H (6KW )- No Water Cooling
an LPM or working as a standalone laserprobe, provide performance
comparable to power meter measurements, at a real fraction of their cost.

Radiation Absorbers
LaserPoint detectors can measure over the complete range of wavelengths interested by lasers, up to many kilowatts of
power and hundreds of Joules of energy. It is thus evident that there is a necessity to use many kinds of different
absorbers to accommodate so many situations.

A-Surface Absorbers- Surface absorbers consist in materials deposited onto substrates that can easily transfer
heat, like copper or aluminium. They are used for CW lasers or other sources that emit long pulses (with duration
>300µsec). Radiation is almost entirely absorbed within a thin layer by materials like special mattes or refractory
materials and then released as heat which flows through the thermopile.

Broadband Coatings: for low powers and general purpose applications LaserPoint utilizes a black coating (BBF)
derived from astronomical research. The power density capability is limited to 200W/cm2, but has the important
advantages of a flat spectral response in the range 0.19-25µm and the bearing of a very high absorptivity (> 96%) over
the entire range.
A general purpose hard coating (HCB) for more demanding applications is used by LaserPoint for mid power lasers. It
can be used over a broad spectral band (0.25-11µm) and some sensors ( as the W-200) bear specially shaped
surfaces that reach a 97% absorptivity by dumping the radiation with multiple bounces. This coating reaches
2500W/cm2 at full power with 300W CW operation. At pulsed operations it can withstand up to 300J with long (msec)
pulses.

High Power Coatings: standard broadband absorbers can hardly withstand the disruptive situations generated by
high power industrial lasers. LaserPoint has developed new high density and better thermal conductivity coatings for
those demanding lasers. On LaserPoint heads from 1KW to 3KW the HPB absorbers can withstand 4KW/cm2 for CO2
in CW operations.
LaserPoint’s HPI coating was developed for even more stringent situations and is applied on the 6KW head; it
withstands 5KW/cm2 at 10.6µm and works in the range 0.8-1.5µm-10.6µm.

Excimer Coatings: LaserPoint has developed a very hard absorber with flat response in the range 190-400µm, ideal
for its use with industrial Excimer lasers. It has also a remarkable high absorptivity at 10.6µm, so it may as well be used
for CO2 lasers. The ridged substrate surface induces multiple reflections that increase absorption to the highest
                                                                                      2
available levels on the market. In the UV the coating can withstand >0.3J/ cm , high repetition rate, nsec pulses at
                                                               2
248nm and has a peak power density capability >20KW/cm .

Coating Damages. The damage threshold is defined as the level at which readings will change more than 1%. When
exceeding this value the absorber surfaces will visibly change colour and the head calibration has to be reconsidered if
the damaged area is important compared to the overall. In some cases a complete substitution of the sensor may be
necessary. Yet, as very often happens, there may be a bleach on the coating but no at all, or just negligible change in
the readings: those colour changes are barely aesthetical and can be accepted without other interventions on the head.

   Light penetrates through within a thin layer of optically absorbing        Light penetrates within the same thin layer of optically
   refractory materials (10-40µm thick ) . Generated heat flows through       absorbing material, as previously shown . During the short

                                                                              absorbers may occur. Volume Absorbers offer far better
                                                                              performances.




B-Volume Absorbers-When heads with surface absorbers are used to measure lasers which deliver short time
pulses ( lower than microseconds), heat has no time to flow and to be removed within the duration of the pulse length.
Radiation remains deposited within in a thin surface layer where it generates a sudden overheating of the absorbing
material and where the excess of energy will often cause ablation.

In those cases the technology of volume absorption is used, where a gradual, exponential decrease of radiation intensity
occurs as it penetrates into the material. Total absorptions are obtained over 0.5-2mm depths rather than few microns:
the consequence is a better distribution of energy and a far lower local temperature increase.

Various types of glasses and ceramics are used by LaserPoint to cover the UV-C range (190-250nm) , the UV-A (250-
400nm) and the VIS-NIR (BB absorber from 400nm to 3µm).Those absorbers can withstand peak powers of
100GW/cm2 and energy densities up to 30J/cm2.

                                          Laser beam                        Thermocouples




                                                                          Cooling

                         Light penetrates and is absorbed by a thick layer of gradually absorbing materials (1-2
                         mm thick) . Heat is generated within a volume and safely flows through substrate to
                         thermocouples and cooling system. Volume absorbers can measure very short pulses
                         and high energies much better than surface absorbers.



Detector-to-Monitor Intelligent Interfacing
Each detector head is a unique device and               has its own
specifications; for example, sensitivity or the voltage output per
incident W or Joule of laser power or energy , is different from head
to head. Its exact value is derived by calibration and calibration data
have to be available to the readout unit to provide accurate
readings. Other parameters, like response times, are also specific
for a kind of head and the monitor must have those values to
provide suitable speed-up of readings. These are examples of
information that each readout unit must get, once a detector is
linked. The question then arises on how to supply the monitors with

All detectors manufactured by LaserPoint come with a DB-15 connector that houses an E2PROM where all relevant
parameter of detectors are stored. It’s LaserPoint Intelligent Identification System (IIS) : the detector automatically
identifies itself to the monitor and stored data are supplied. The monitor knows what to do, whether it is a 3W or a 6KW
head.

This technology has another advantage, with a relevant budget impact: all detector heads from LaserPoint can be
easily interchanged with any of the monitors and one single readout can be used with all detectors in the lab.

Selecting a Power or Energy Measurement Solution
Measuring power or energy can be done in many different ways and to obtain either basic or complex information. In the
majority of applications it is done by the commonly known power/energy meters, by laser probes or OEM sensors. In
each case the finality may the same (e.g. knowing the laser power) but real, final needs may be very different, as well as
their consequent economical aspects.
 A power/energy meter is made of a detector linked to a monitor via a special connector, storing all relevant data
concerning the head. The monitor can work as a stand alone unit displaying the power/energy values and other
information and can be connected to computers or chart recorders.
Power/energy meters are high end instruments whose performances may vary with the number of features or
complexity of the overall setup. Prices will follow accordingly . They are measurement instruments, the which thing
means that they have to undergo to classes of precision, must have tight values of repeatability, need to be periodically
re-calibrated (at least once a year) to trace their performance.
For powers exceeding 100W the heads need an internal cooling system which could be a fan extracting heat from
dissipating fins or water running through channels carved into the head. This is because power/energy meters must
work continuously for long periods of time facing the laser beams, even many KWs, without problems. Their reliability
and capacity to work indefinitely at the maximum powers or energies makes them the ideal instrument for applications
like:
-Measurement of laser or laser system stability
-Alignment of laser cavity
-Alignment of optical setups
-Measurement of losses
-Derive statistical information on laser behavior
-Measure the power/energy ratio between 2 optical paths
 Doing all this is only possible by the association of a properly cooled detector with a complex electronics which reads
the row data and elaborates/displays the measurements. Once the measurement session is over, the equipment can be
easily removed and used elsewhere, with another laser or system.

This is not so with OEM detectors. OEM detectors use the same sensors of power/energy meters embedded in
simplified housings; they respond to the need of laser manufactures (in the majority of cases) to have a continuous
monitoring of their sources and are permanently fixed into the laser head or the laser machine. But we are now talking of
monitoring and not fine measurement: the associated electronics is in general very simple and limited to convert the
sensor output into a signal manageable by the laser control unit. The power/energy value is displayed, maybe after
basic signal treatment (e.g. the speed-up of response time) but no significant elaboration is made. Measurements are
accurate and repeatable but the display of information is used to preset the power/energy levels necessary for an
application , verify that set levels remain as fixed and no problems occur on the machine.

Laser Probes only read power. They make a measurement in a fixed time period and are used to make time-to-time
controls at the source exit, at the working area or before/after an optical component to check its losses.
Probes simply tell which is the power level at the time of measurement, like a photo camera provides the picture of a
shot taken at a certain instant; on the contrary power/energy meters can be imagined as movie or video cameras that
show a real time and continuous evolution.
For the above reasons probes cannot be used for alignments, monitoring of stability or provide statistical information
which all require a continuous use .
They are low cost devices and, until the introduction of LaserPoint’s Cronos and FIT series with their patented
measurement and acquisition techniques, the market was only offering poorly repeatable and precise instruments.
FIT and Cronos have been the real breakthrough in this kind of measurement with the reduction of reading time
(lowered from 20 sec or more to 4sec and 8sec) , the possibility of making several measurements without cooling and
the complete automatism of measurement which makes them independent from errors generated by wrong timings.
All these innovations have now brought those probes to have performances comparable to power meters (e.g. the FIT
instruments have the same capacity of a power meter to repeat measurements with a ±1% error bar).

            LP-EXPLORER: the Detector Finding
                      Program
On the web or on the CD ROM with your catalogue
Our new EXPLORER program will let you find, in the easiest way, the proper heads that meet your measurement
needs. Just by entering the laser parameters EXPLORER will calculate the power or energy densities specific for that
beam. It will finally relate these values, together with the other laser data and available detectors, to define and display
which heads, monitors and coatings can be used.
EXPLORER can be either downloaded from the web or from the CD-ROM with your catalog.
From the Catalog CD: go to Start>Run>X:\LP-Explorer\setup.exe (where X stays for the CD-rom drive number).Click OK
and follow the instructions. After installation is completed, you may run the Explorer application from your desktop.




Using the Explorer program is then all easy.

There are a few initial steps to be performed before entering the beam parameters:
1) -specify the laser type: CW or Pulsed.
2) -indicate the beam shape. Heads are chosen considering their sensitive diameter always to be at least 16% larger
                                                                             2
than the beam itself; infact, most of times beam sizes are specified at 1/e , leaving a lot of energy-which must be taken
into account- available outside the nominal size.
3)If “Pulsed” has been selected, the type of measurement to be performed has to be chosen, then: in “Only Power” the
program will find heads and monitors which will measure only the average power. Vice versa, by selecting “Power &
Single Pulse Energy” the program will decide which heads & monitors are available to measure both the energy of a
single pulse and average power; for a correct measurement of avg power the repetition rate has to be > 3 Hz.
4)The last selection to be done is the kind of desired product: if the application involves long term measurements, laser
alignments, the necessity of making statistics on measured values, etc then chose “Power & Energy Meter”. If the
application is only a periodic check of laser power, then a “ LaserProbe” is probably what better fits your needs.

Input Beam Parameters, Explore and Reset Data keys

In this frame you’ll need to enter your beam data with the appropriate
measurement units.
For a CW laser you will only need to insert Beam Diameter, Wavelength
and Max Power.
For a Pulsed laser it is necessary to add Pulse Width, Repetition Rate
and Max Energy. Once all boxes have been filled , just click on the
Explore key to obtain all information .
If another type of measurement has to be done, e.g. at another
wavelength, you can refresh the screen by clicking on the Reset Data

Derived Beam Parameters
This frame shows several important calculated beam parameters derived from your input data and will give a synthetic,
yet exhaustive, picture of your beam .

Available Heads& Coatings, Damage Threshold at:
All detectors that fit with specifications for your beam parameters are shown and, to simplify selection, head types are
separately listed in their various versions of coatings or absorbers. Aside the head model is reported the corresponding
level of risk of damage for that coating/ absorber when subject to the inserted laser parameters. This value is expressed
as a % of the damage threshold.
It will undoubtedly result that some detectors may be closer to the damage threshold than others : always prefer a head
which is below the 50% of damage threshold. This will put the coating on the safe side from hot spots and compensate
from laser modes.

To proceed on your selection you may single click on each head model to open the “Power/Energy Resolution with
Monitor “ frame; a double click will open a pdf file showing both specifications and a mechanical outlook for each head
of interest.
Some additional selection criteria are more personal and depend on the way the head will be used or the kind of
application; for example LaserPoint manufactures a series of compact heads designed to work intermittently or for short
periods. They are the heads with double code (e.g. the A-40/200 series) which can extend their measurement range,
repeatedly but intermittently, These heads have a temperature sensor and , when associated with PLUS/ LPM monitors
, can be used until a COOL message is displayed
.
Power/Energy Resolution with Monitor
This frame displays another important information which has to be taken into account when selecting a detector: the
power or energy resolution provided by a complete measurement setup. Resolution depends on the noise of both
monitor and head and can be seen as the least value which can be read having a practical meaning.
Whenever a monitor is then available for the selected detectors ( if not, a n.a.. is displayed), the box underneath each
monitor model reports the achievable resolution.
Always consider what the frame reports, both for determining which monitor has to be used, but mostly to be aware of
the real minimum values ( at least 10 times the resolution) of Power/ Energy which can be read.

Coating and Absorber Curves Characteristics
The program also lists the absorption and damage threshold curves for coating and absorbers used by LaserPoint .
Once you have selected a head with its coating or absorber, you may click on the side key to visualize , as pdf files, the
complete performance of the coating/ absorber itself.
This additional check can be very useful if the head is intended to be used at other wavelengths or with different pulse
lengths.

                           Calibrations at Laser Point
NIST and PTB Traceability
Sensitivity , or the voltage signal delivered by a detector as a function of striking laser power or energy, is different form
detector to detector for different reasons one of which is the spectral response of absorbing coatings: the percentage of
absorbed radiation is never 100% at any wavelength, but is a lower value which changes with the wavelength itself .
Sensitivity undoubtedly depends also on manufacturing variables but it also happens that power and energy meters
change their properties with time, as environmental factors – usage in particular-, degrade or damage parts critical for
an optimum performance.
In order to grant precise measurement accuracy, LaserPoint supplies each of his instruments calibrated before delivery
to the highest level of accuracy, with traceability to the National Institute of Standards and Technology (NIST)
Laboratories in Boulder, Colorado (USA) and the Physicalisch-Technische Bundesanstalt (PTB) in Berlin (Germany).
All LaserPoint detectors are subject to this Nist and PTB traceable calibrations and a Certificate, reporting the list of
NIST/ PTB standards and instruments used in the calibration procedure, is supplied to prove it.
To ensure that accuracy and performances of laser power and energy meters remain intact over the time, a regular
schedule of calibration and preventive maintenance is needed. An industry standard is to recalibrate once a year: units
can be shipped back at LaserPoint where, at a modest fee, a general check-up and recalibration of the detector will be
done .

Calibration Capabilities in LaserPoint
LaserPoint owns a number of laser sources which are
used for in-house calibration ; these sources cover                PTB Linearity Measurements for W-1000

How to read products ID code and select a detector head
To ease and speed up your selection we have assembled codes that synthetically describe the detectors; we just ask
you to complete these codes adding the type of measurement and the wavelength of calibration . The complete code
, to be used when asking for quotes or when ordering, is then straightforward and gives an accurate, synthetic and a
no-doubt description of the heads and the way it is going to be used , which helps LaserPoint to serve you better and
faster .

Head codes , as you will find on the catalogue or given by the LP Explorer, report a string which synthesizes the head
basic features :
1-Firstly we identify the cooling type.
A stays for air cooling (which can either be by convection or forced: please check on the single head specs ); W stays
for water cooling.
2-Then we identify the full scale power (e.g. 200 means that the head can withstand up to 200W).
Some of the new heads have a double code separated by a / . (egg 40/200) : those are heads with sensors capable to
withstand many times the max nominal power, in case of short term use.
In these cases the first digits identify the maximum power on continuous operation; the latter digits report the max power
when the head is used for a limited period .
3-The sensitive Diameter (D XX) is also displayed .Some detectors may have the same power but different acceptance
areas as they have been developed for different applications. Chose which fits better for your case remembering that
nominal beam diameters are always given to include the 86% (1/e2) of the beam energy. Real beams are larger !
4- The last digits show which coatings or absorbers types available for each type of head. Sometimes more than one
coating is available for that head. Select the model with the most suitable coating for your application: egg – HCB. For
any doubt refer to coating specifications or take advantage of the LP Explorer .

The following are the additional information we ask you to add:
5- Measurement Mode : detectors can be configured to work as Power Meters (P), as energy meters (E) or both (P+E).
When constructing the code, specify which are the measurement modes of your necessity : e.g. -E
6-Calibration Wavelength :select from the tables in the Ordering Information the kind of available calibration
wavelengths and add it to the code: e.g. -VIS

Plug-In Modules for 20mW or 200mW full scales
These modules, when plugged to the smart connectors of Laser
Point’s A-02-D12-BBF heads, reduce the head’s full scale to 20mW,
allowing readings with 10 µW resolution.
When connected to A-2-D12-BBF/ A-2-D12-HCB heads brings full
scale to 200mW, allowing readings with 100 µW resolution.
The A-02-D12-BBF and A-2-D12-BBF/ A-2-D12-HCB heads, with
the simple addition of these 2 optional modules, will become the
most versatile tool for low power measurements .

 Mod AD20 sets the A-02-D12-BBF
 heads to 20 mW f.s.

 Mod.AD2000 sets the A-2-D12-BBF/
 A-2-D12-HCB heads to 200 mW f.s.

Applications of Power and Energy Heads
Measurement of long term stability
Long term verification of stability , necessary for example for the final validation of a laser source, is made by directly
placing a power meter head , e.g. associated to the PLUS monitor, in front of the laser. The main screen of
PLUSSOFT shows the long term behaviour of up to 12 hours. Plus and PlusSoft also have the possibility to set hi and
low alarm thresholds .


          Laser




Alignment of laser cavities
Alignments require continuous tweaking of cavity mirrors: during these actions values change very quickly and
understanding whether tuning is improving or not need a proper tool. Digital displays, with their fast running numbers are
very un-easy; on the contrary, analog displays with their moving needle require a lot of attention to catch the value.
Bargraphs are of great help to provide an immediate feeling of the direction of alignment, like in LaserPoint PLUS:, to
have a fast perception of tuning direction at the same time maintaining the possibility to read the reached value.


            Laser




Alignment of optical set-ups
Optical losses can be introduced by a number of reasons, like the non correct angular positioning of elements or by
damaged components; more often a sensitive decrease of throughput can be reached by misalignments or simply by
summing individual losses of optical components. A power/energy meter positioned along the beam path, permitting
correct alignments and verification of losses, optimises yield and efficiency of the optical system.


          Laser




Measurement of losses
Verification of reflectivity, transmission and losses of beam splitters, filters and other optical elements can be done by
inserting a power/energy meter in front or behind the component. Dynamic changes, like modification of behaviour or
performances under the action of temperature variations, can be also monitored.

Statistical measurements of laser or laser machine behaviour
Statistical measurements are used for monitoring quality aspects of a source, a laser machine or set-up. Having for
references heads bearing a NIST (National Institute for Standard and Technology) and PTB (Physikalisch-Technische
Bundesanstalt) traceable calibration , data can be used for internal files, for quality reports, can be added to manuals or
given to customers. All relevant statistical information as Current Value, Min &Max Values, Average, RMS Stability,
Standard Deviation are supplied by the PLUSoft on measurement periods as long as required. For easiest handling,
all statistical data can be transferred and saved on files or printed

Selecting a meter for the application
The first step in defining a measurement system is to choose the detector needed for a specific application.
The following step is the meter selection which may be based on the following three basic considerations:
a)-where the meter is going to be used. For example, if the operator is a service engineer who spends most of
his time in the field, then he needs fully portable and rugged equipment for quantitative measurements and
laser alignment. Laser Point’s PLUS is the small, battery operated meter designed for those applications.
A different case is when the laser machine needs an internal monitoring system which will be used to verify
the constancy of preset parameters, to predict maintenance of beam line components etc. For these
applications the tool is the Laser Process Monitor ( LPM)
b)-which are the needed additional features. If the requirement is the use of a power meter for the final
validation of a laser system before its delivery to the customer, it may be then necessary to do advanced
statistical analysis .Laser Point’s PLUS-SOFT or LPM-SOFT powerful analysis software extend
measurement capabilities
c)-foresee future developments. Perhaps in a near future a new laser machine will be purchased in the
Company and the necessity to use different heads, e.g. for high and low powers, will arise. The PLUS
offers this possibility, since it mates with all LaserPoint detectors, via its IIS (Intelligent Identification System)
The following at-a-glance table will help in a first selection.

              Laser Power and Energy Meter: the PLUS
The PLUS model is a meter for advanced power and energy measurement that mates to all LaserPoint
detectors via a proprietary Intelligent Interface System (IIS )connection. It is
sufficient to plug the head connector into the meter port to get a calibrated
instrument, already configured for the measurement. One of the great advantages
of the IIS connection is that , should a new head be added to the lab equipment
or to the system, the existing monitor can be used with that new head; in other
words any Laserpoint detector can be associated to a PLUS monitor if
measurement requirements become different.
The PLUS then converts the output voltage signals from detectors into accurate
readings of power and energy or supplies other valuable information by means of
its additional software.
The PLUS has been structured to match to a very broad range of applications and
any customer budget .

Unbeatable Price to Performance
Easy and immediate:
The PLUS is the most versatile measurement monitor for thermal heads existing on the market today. Its price and
performance are absolutely outstanding , since it has been specifically imagined and designed to be the tool for laser
measurement available to every laser operator.
The PLUS can be plugged to any of LaserPoint detectors by means of its standard Intelligent Interfacing System (IIS) .
The instrument can be governed just by means of three soft-touch keys:
-ON/OFF (Zero). During a measurement session, the key will also Zero stored measurement values and display.
-T/P. Gives access to the Tuning Function and the Power Measurement Function.
-E. The E key provides access to the Energy Measurement Function .
The mw/ mJ leds, associated to the low Power/Energy Measurement Functions, are only enabled by information
stored within the detector E2PROM.

Power, Energy, FIT Operational Modes:
 PLUS can work on different operational modes. It can be used as a power meter, as an energy meter or as a power
probe up to 6KW , when working with the FIT heads.
The selection is automatically made by the monitor when it reads the detector E2PROM, when the unit is switched on.




Temperature Compensation:
Ttemperature compensation is made after an incoming signal from a temperature sensor located within the detectors, by
the PLUS to linearize the head response and advise, with a warning message on the display, when the head has
overtaken its max allowable temperature.

External Interfacing:
PLUS can dialog with the external PCs, plotters, etc via its Analog Output (0-2 Volts) or RS232 digital interface, which
are provided as standard.

Tuning:
Through this function, a high resolution laser tweaking can be done. The existing power level is then displayed, together
with the bargraph, positioned at its center; it will move downward or upward depending on tuning.
The smaller digits shown on the display are the variations, in percent, from the initial power value




Additional features
The E2PROM, housed within the IIS (Intelligent Interfacing System) connector, stores wavelength correction values
based on spectral data measured from each coating or absorber. The PLUS display will show :
EXC : for the UV and excimer laser range (250-350nm)
VIS: for the visible range (400-700nm)
LD: for the Laser Diodes range (800-900nm)
Yag: for the Nd-Yag wavelength at 1064 nm

 UCF:( User’s own Re-Calibration Factor) The User Calibration Factor gives customers the possibility to modify the
value of original calibration sensitivity from 01.% up to 999.9% (or from 1/1000 up to 10 times). It can be selected when
scrolling for the wavelengths
The UCF can be used :
-in case of light damages on coatings
-in case of detection after partializing devices (e.g. filters, beamsplitters, mirrors) to track the main beam
-have measurements aligned to other references
The UCF is effective on each measurement mode of Plus (power , energy, Fit) .

               Smart Head to USB Interface: the PC-LINK
Your Laptop or PC Converted Into a Power/Energy Meter
LaserPoint introduces the PC-LINK, a smart head to USB interface that converts any
PC or laptop into a real, powerful laser power or energy meter. To make it work it is
sufficient to install the software, connect the head to the interface unit and this latter to
the USB port of a PC. No external power source is needed.
This sophisticated monitor is plug and play with all LaserPoint smart heads and has
been designed for service and laboratory applications offering the convenience,
flexibility and value of computer-based operations.
PC-LINKs are supplied with LaserPoint’s user-friendly communication software package.

The Rich and Flexible Monitor
                                      The very compact size and low weight of PC-Link, together with its advanced features
                                      make this monitor the ideal partner for service applications or laboratory use. The
                                      PC-LINK is also the candidate for use in laser machines, in particular when
                                      associated to LaserPoint’s FIT detectors that work up to 6KW without the need of
                                      water cooling.
                                      The use of PC-Link is straightforward. The unit will recognize the power/energy head
                                      as soon as it is plugged-in; furthermore, the PC-LINK will use its anticipation circuitry
                                      to insure a fast response and will auto-calibrate by using the data stored in the
                                      intelligent connector (IIS) to provide the most accurate measurement .
                                      Another feature is the access to the User’s Own Calibration Factor (UCF) and a X10
                                      gain for enhanced measurement flexibility (eg low power measurement to 20mW fs).
                                      The software supplied with the PC-Link allows to measure, analyze with full statistical
                                      functions (Min., max., mean, and standard deviation) and record power and energy
                                      from all LaserPoint heads without the need of a display. Data from each detector can
                                      be logged simultaneously to file.

                    Laser Process Monitor: the LPM
The System
The LPM is a fast and intelligent power and energy measuring setup that bears
various outstanding features like the reading at 6KW without water cooling, generate
alarms if a preset working value has been overtaken, provide measurements in 1-
2 seconds in the multiKW ranges or the being completely opto-isolated, since it has
been designed for the industrial environment .
The major application of LPM is to make measurements of laser powers and laser
energies at the workpiece during parts exchange or working downtimes to check or
document the laser power or energy without reducing productivity in the
installation.
The major advantages of this unique approach are: to know the true power or
energy really delivered for the application, independently form absorptions, optics
losses, dirt, etc. A second major advantage is that monitoring at the workpiece will
provide a synergic effect due to the combination of information coming from both the
process area and the laser controller: in this way the LPM , will help to implement a
predictive maintenance and improve laser machine and process reliability .

An LPM setup is made by the electronics, a detector and the application software.
Detectors associated to the LPM can be installed at any convenient location on the
working area or along the laser beam path, e.g. after a beam splitter. Any detector
from the LaserPoint catalogue can be associated to an LPM and no special
detectors are required.
The LPM electronics is a real industrial tool, being completely opto-isolated, thus
immune from any E.M. pick up and each of its section having an independent
voltage supply .
The LPM electronics can be supplied as an OEM board or as a cased, CE marked
version; both can be applied on standard DIN slides and are then pluggable within
any industrial cabinet with total ease.
LPM setups are in-house calibrated against NIST and PTB secondary standards
and are shipped with test certificates.

                                                                allows to set
alarms for process monitoring or system malfunctioning, to carry out
statistical evaluations on running measurements, to save and download
data.
An additional important feature available on the LPMSoft is the User’s Calibration Factor (UCF) which gives customers
the possibility to modify the value of calibration sensitivity from 01.% up to 999.9% (or from 1/1000 up to 10 times).
The UCF can be used :
-in case of detection after partializing devices (e.g. filters, beam splitters, mirrors), to track the main beam
- to make measurements aligned to other references
Local operation
It is the most simple configuration of LPM which will only
generate alarms, e.g. triggering an alarm lamp or horn.
The LPM monitors the laser power/energy and checks
whether it is within two acceptable (Min/Max) threshold
values, preset on the electronics itself. The gap between
those two values defines the           power/ energy range
acceptable for the laser application.
The Min/Max values are stored in the LPM memory by a self
learning algorithm, simply exposing the associated detector to
the laser beam, set at what the 2 alarm levels will be.
If the power/energy values exceed those previously
established, a relay (e.g. connected to the laser PLC)
switches off and generate the alarm . Additional alarm LEDs,

located on the board will warn, turning from green to red.
In case it is necessary to know the power/energy values, two additional analog outputs ( 0-10V and 4-20mA ) are
available for the purpose (e.g. by using a Multimeter).

Detectors for LPM- LPM electronics can work with all kind of detector heads manufactured by LaserPoint and in
Power, Energy and LaserProbe measurement configurations:.
This adds a superior flexibility and expands the range of applications to the system. The customer may decide which
final configuration he needs, looking at the system constraints but never worrying for his budget.

-Power Meter Mode: This mode allows a continuous measurement of laser power. It helps during machine
settings, can be used to monitor long term laser stability, optics alignment, etc. When laser power exceeds few
hundreds Watts, detectors used in this configuration have to be water cooled . Operating range is from low powers up
to 10KW.

-Laser Probe Mode: the OEM laser probes (Fit Series) allow power monitoring done on short laser exposures. This
measurement mode is carried out by special detector heads and a patented methodology that allows automatic
measures made in just 4-6 seconds, depending on the head model. The range of operation is from 50W f.s. to 6KW
f.s..
Together with lower costs for the detectors, another major advantage is that there is no need for water cooling even at
multi-kW powers
These measurements can be programmed between working cycles to check the constancy of laser power, after
resetting parameters (e.g. before cutting or marking new materials), after components have been changed or realigned,
etc. In practice, whenever long running measurements are not necessary.

-Energy Meter Mode: This mode is used to measure single shot pulses. Typical applications is monitoring of
marking or micro welding or on aesthetics and medical systems . Available ranges go up to 300J

                 Applications of Laser Process Monitor (LPM)
Operation in Remote Mode
The LPM detector head (1) may be located as permanent unit in a non used corner within the process area or any other
spot, within the laser system or machine , where monitoring is necessary. It is important that the beam be large enough
not to damage the detector absorbers ( the detector can be fixed a few centimeters underneath the focal plane so that
it will be sheltered from moving carriages and is of no disturb to the process).
The acquisition and processing board is housed in MR9 slim card case (2) plugged on standard DIN rails, available on
any industrial cabinet or rack. It interfaces with the laser PLC or an external PC with a protocol Mod-BUS through the
serial interface RS232. A powerful, yet friendly, software interface (3) allows to read the power or energy values
delivered at the process area , set the alarms, carry out statistical evaluations, etc in the Power, Energy, Probe
configurations.
Whenever preset alarm thresholds are overtaken, visual messages are displayed on the screen or alarm signals can
be custom used e.g. to stop the process.
During the phase of machine validations, beam delivery alignments or whenever measurements of long term stability
are made, the software of LaserPoint LPM can show on a large graphical screen, the time evolution of power in
measurement sessions which may last many hours. Should a high resolution be needed to look at events occurred in a
short period (e.g. a sudden power drop), a zoom function can be used to observe on a tighter time scale. The Statistical
Functions screen is an even more powerful tool during long term monitoring since it provides all relevant data like Min
and Max values reached during the measurement period, the Average value of measurement, the Standard Deviation
and the Root Mean Square values.
Data can then be saved, with day and hour of measurement, to be used as a documentation for final reports or for the
customer.

Operation in Local Mode
The LPM detector head (1) can be placed in a remote area close to the process or in any other spot, within the laser
system or machine , where monitoring may be necessary.
 The acquisition and processing board is housed in MR9 slim card case (2) plugged on any standard DIN rail, within
the control unit or any other place where it may be useful. LPM can monitor the laser power (or energy) and checks
whether it is within two preset threshold values. Measured values can be read via a 0-10V/4-20mA analog output and
trigger alarms via a potential free contact. Those signals can be used to switch alarm lamps or acoustic signals (3).
Alarm thresholds are set by a self learning algorithm while exposing the sensor to the laser beam tuned at the MIN-
MAX power or energy alarm levels.
Operating in Local Mode is particularly useful in case of retrofitting the LPM set-up on older machines, where the
integration of its SW is not possible.

Operation in the Probe Mode ( periodic power check) Measurements runs can be planned to accomplish short
controls of beam power during working cycles, after laser parameter resetting, optics realignment, etc. The use of
special FIT (Fast Integrating Thermopile) heads (1) that do not require any water cooling , even a many kW , is of great
help in many industrial environments where having water at the application area is a problem. The acquisition and
processing board is housed in MR9 slim card case (2) plugged on any standard DIN rail and housed in industrial
cabinet or rack. Data can be analysed (3) by the specific SW for the Probe Mode or, should immediate warnings be
needed, visible/ acoustic alarms can be triggered.

Predictive Maintenance
Prediction of incoming failures ,e.g. at optical components, can be easily done by cross checking the power/energy
delivered by the laser source and what is effectively delivered to the work piece. A too high difference between the two
values may indicate that damages already occurred.

Beam Delivery System: Alignment & Stability
The complete beam path can be aligned and verification that the max yield at the work piece has been reached can be
done with LPM working in the power/energy mode. Successive measurements of system stability can be done and
visualized with the most relevant statistical information on the beam behaviour.

Monitoring of Marking, Micro-welding, and Micro-Machining Systems
Monitoring of energy or power as they are delivered after the focusing lens, providing a fast and direct control of the
correct values for the process, of the optical system or optical fiber integrity can be done with LPM simply displacing the
optics or the translation stages.

Control of Working Cycles
Setting of working cycles with measurement of the power really delivered to the work piece can be done with LPM ,
operating in power mode. It can be done as a simulation before working, to verify the correctness of process
parameters, or in certain phases decided by the operator, e.g. during the dead times between welds, to check that
preset parameters did not change for reasons like optics damage, dirt, etc.

                         OEM and Custom Products
A growing, customer- driven OEM manufacturer
Since long more than a decade LaserPoint has been supplier of OEM
power & energy sensors to some of the world’s leading laser
manufacturers. Our presence in the OEM market, several patents and the
participation to a number of European Projects on laser monitoring are
the best cards LaserPoint can give his customers, either in supplying
standard products or in providing technical support in the discussion for
new applications or the design of new detectors.
The following table shows the basic characteristics of LaserPoint most
popular sensors. Around those sensors complete heads are designed and
supplied with housings, cooling systems and amplifying electronics based
on Customer’s requirements and specifications.


 Advantages of LaserPoint OEM Laser Measurement Products
  Reliable and Versatile Measurements Tools
  OEM sensors discs manufactured by LaserPoint are
  high sensitivity, low impedance thermopiles. High
  sensitivity is important to maximize the signal-to-noise
  ratio when working at low powers .

  Compared to other types of sensors which might be
  used in equivalent applications, thermopile detectors
  can be applied directly onto the beam, even at high
  powers.

  LaserPoint sensors are made with resistant materials
  and coatings that extend their applicability from UV to
  Far Infrared and to concentrated beams, without
  damaging even at extreme power densities.

  LaserPoint provides thermopiles which exhibit a high
  degree of linearity over their entire working range and
  have large areas that sample the whole laser beam.

  Thermopile sensors are almost insensitive to the
  position and the size of beam when it strikes on their
  active areas. Alignment is never critical and installation
  time in OEM applications is fast.

  Everything has been designed to provide accurate and
  reliable measurements of lasers like CO2, Excimers,
  Laser Diodes, Nd-Yag       from 3W to 200W at
  competitive pricing .

  Compact Design
  Off-the-shelf sizes of sensor discs range from
  15x15x3mm to Dia 90x6mm, with active areas up to
  40mm.
  Calibration
  All OEM sensors undergo to a series of five in house
  inspections and controls, which include individual
  tests of sensitivity and impedance. A full calibration,
  with NIST or PTB traceability, is available on request.

  Technical Support
  If you do not find what you need today we can design
  custom sensors, housings and electronics that fit your
  requirements. Ask our Application Engineers for
  technical support: we have a full knowledge of optics,
  lasers, thermal behaviors, materials to cover your
  requests.
  A commitment to servicing with quality products,
  prompt deliveries and after sales assistance is another
  support provided by LaserPoint on which customers
  can rely on.

Select Connectivity Options
Output connector options include Laser Point’s IIS (Intelligent Identification System) on DB15 connector, BNC, Molex
and 2 or 4 wire pigtail.
-The DB-15 houses an EEPROM which stores calibration corrections
and other head relevant data. We provide for use with LaserPoint’s LPM-OEM, LPM-CE and PLUS power and energy
readouts.
- BNC connectors give, total plug/un-plug ease and high EMI noise shielding.
-Molex connectors make easier the removal of detectors for service or for their use at other locations
- Pigtail: 2 or 4 wires, depending on models, deliver the natural signal of sensor discs or heads to a control unit or host
system .

                         Applications of OEM Sensors & Heads
A-Thermal Sensor Disc and Heads

Laser source monitoring
This is by far the most popular application of OEM heads. They are placed behind laser rear mirrors and catch the <1-
2% radiation leaks exiting from these mirrors; that amount is strictly proportional to the total emitted power so its
measurement results to be very reliable. Given the small leakage fraction, multi-kilowatts sources can be continuously
monitored by low power sensors. Though the final validation of a laser source, including the calibration of its internal
power sensor, is made by a power meter, yet OEM sensors provide successive field monitoring, are used for later
alignment purposes and setting of process parameters.

                   OEM sensor:Vout to control unit
Fiber monitoring
Monitoring the integrity of fibers delivering Nd-Yag, Diode laser, medical lasers beams, either at high powers or low
powers, can be done by picking up the residual beam portion (< 0.5-2%) non reflected by the total 90º mirror in the
focusing heads.


                                                               0.5-2%

On-line monitoring
On-line monitoring can be easily achieved by exploiting the leaks of existing optical elements or keeping dedicated
components (like beam splitters, filters, diffractive optics, etc) into the beam path.


                                                               OEM sensor:Vout to control unit

Beam dump
In some medical applications the laser must be kept running at its working power or energy even when it is not in use for
treatment. The necessary power/energy must be immediately available for the short periods of application and there
must be no delays (e.g. warm-up times ). OEM heads are used as beam dumps for the non-operating periods and an
extractable mirror releases the beam for the application.

Sampling at measuring port
Several medical machines bear a port for time-to-time measurement of laser power or energy. In Countries like the US
it is a precise requirement from FDA to have a monitor for each laser on-board the machine. OEM heads are plugged
into the ports to read the power or energy available for treatment exiting, e.g. from optical fibers. Moreover, since optical
fibers or fiber tips crack very easily, frequent checks are a wise solution.

B-OEM Laser Probes
Operation in the Probe Mode ( periodic power check) Measurements runs can be planned to accomplish short
controls of beam power during working cycles, after laser parameter resetting, optics realignment, etc. The use of
special FIT (Fast Integrating Thermopile) heads, which do not require any water cooling even at several KWs, is of
great help in many industrial environments where having water at the application area is a problem. The OEM laser
probes are perfecy for use with the LPM electronics whose acquisition and processing board can be plugged on any
standard DIN rail and housed in industrial cabinet or rack. Data can be analysed (3) by the specific SW for the Probe
Mode or, should immediate any immediate warnings be needed, visible/ acoustic alarms can be triggered.

Periodic controls in manufacturing
Periodical monitoring and control of power in laser cutting or welding machines. The LPM software allows the setting of
alarm thresholds for a GO/NO GO of manufacturing process

Predictive Maintenance
Prediction of incoming failures ,e.g. at optical components, can be easily done by cross checking the power/energy
delivered by the laser source and what is effectively delivered to the work piece. A too high difference between the two
values may indicate           that damages already occurred.

                                               Fit and Cronos
Many applications do not require the tight specifications of power meters. For others it is simply sufficient to make quick
checks and there is no necessity to measure over an extended period of time; while it is sufficient to have readings in a
snapshot just to monitor if power is ok. Sometimes water is not available on the machine. Many times it is a bare matter
of limited budget. That’s the world for a different class of instruments known as laser probes or power probes.
Those instruments are stand alone units made of a thermal probe connected to an electronics and its display. In
general, existing instruments of this type are thermometers that measure a temperature difference in a fixed time and
have a simple dial or a digital display. They have a number of major drawbacks, like their dependence on
measurement time, which in most of cases has to be evaluated by the operator, their poor repeatability or accuracy, the
fact that after each measurement they need to be cooled, etc.
LaserPoint has introduced a real breakthrough in the field with two new series of fully automatic laser power probes
that calculate laser power by a microprocessor based measurement of temperature dynamics. Their measurement and
acquisition technique self-determines the time needed to carry out a measurement: data acquisition is triggered and
stopped by detecting set heat parameters thresholds. This technique is totally free from induced errors due to
measurements of exposure times and may allow multiple measurements without the need of forcing cooling to the
absorber.

Both Fit and CRONOS feature a large multifunction LCD that simultaneously indicates the
measured power, the wavelength of calibration (CO2, Nd-YAG) and low-battery. Furthermore a
moving bar shows the actual absorber temperature; this informs the operator whether he can still
perform more measurements before the absorber reaches its maximum allowable temperature and
needs to be cooled. Additionally, the probe status is displayed by a two colour LED: probe is ready
(steady green), measurement is in progress (flashing green), measurement is over (steady red) or
cooling is needed (flashing red).
Fit and CRONOS are both operated by a single button. They store the last measurement in memory
and shut automatically off after 5 minutes of non operation. Two common AA batteries allow a
minimum of 5000 measurements.
Fit and CRONOS have been ergonomically designed in all their details like the LCD display and the
balance of weights, to provide a comfortable and safe operation. The absorbers feature low
reflections and high damage thresholds; in particular the hi-power, multi kilowatt CRONOS have a
concave conical shape to avoid dangerous back-reflections toward the operator.
Recalibrations can be made user.
 Fit, with its low profile sensor head connected to the display body by 1m extensible cord, allows
remote testing even in tiny spaces.

   Fit-IPL:Energy & Power Meter for IPL (Intense Pulsed Light)

Fit-IPL is a fully automatic, hand-held energy and power
meter designed for IPL (Intense Pulsed Light) applications.
Fit-IPL works on a microprocessor based patent pending
measurement technique of temperature dynamics through a
thermopile sensor; measurement and data acquisition are
fully automatic, making this technique virtually free from
operator induced errors.

  Fit-IPL can measure both flashlamps single shot energies
  up to 300 Joules and average powers, when in burst
  mode operation, up to 30 W.
  Fit-IPL innovative measurement concept reduces the time
  of measurement and display to 10 sec. with excellent
  repeatability (±1%), accuracy (±3%) and high resolution
  (10 mW up to 30-W full scale) associated to a wide
  dynamic range of measurement (down to 1% of f.s.).


                           Fit-IPL is extremely friendly in use and features a large exposure area (Dia=60mm) to match
                           with all handpieces. The broadband detector works in the range from 400 to 1400 nm, which
                           is the range of interest for the majority of applications (photoepilation, skin rejuvenation,
                           treatments of acne, vascular and pigmented lesions, psoriasis).
                            The absorber coating of Fit-IPL remains fully responsive also when filters are used to reduce

the lamp spectral bandwidth. This absorber is very robust, as it has been designed to face the
extreme fluences (up to 90J/cm2) of professional systems (medical and clinic) where the
highest pulse energies are involved. But it is also very flexible since it can operate with semi-
professional systems (beauty salons) and consumer-oriented systems (2 to 10J/cm2).
Fit-IPL bears a multifunction LCD that simultaneously indicates the flashlamp energy (or
power) delivered by the handpiece, the instrument mode of operation [Sin for single shot
(energy) or rEP for repetitive (power)], probe model and low-battery warning. A bargraph shows the sensor temperature
to inform the operator whether he can still perform more measurements before the sensor reaches its maximum
allowable temperature. Additionally, the probe status is displayed by a two colour LED indicating if the instrument is ready
for measurement, if the reading is in progress or over and if cooling is needed.

                             Fit-IPL is operated by a single button; it shuts automatically off after 5 minutes of non
                            operation and always stores its last measurement in memory. Two common AA batteries
                            allow a minimum of 4000 measurements.

                           Fit has been ergonomically designed in all its details: the low profile thermopile sensor head,
                           connected to the display body by 1m extensible cord, permits remote testing even in tiny
spaces. Another important feature is recalibration, which can be made by the user.

                                 Applications of LaserProbes
Laser Probes can be used in a variety of applications. Up to now they have been the standard measurement tool for
service engineers who could rely on their portability, ease of use and quick measurement time. The new generation of
probes manufactured by LaserPoint extend their range of applications and makes them available to laser technicians of
any level , to any industrial job shop for internal controls, for periodical controls of medical equipment.
This is due to the number of advantages that both FIT and Cronos probes offer, when compared to old generation
equipment.
For example a high degree of measurement repeatability is necessary to verify whether a source is stable or is drifting
or whether the best available power has been reached after an alignment session . On standard probes, who have an
error bar of 10% ( +/-5% ) , such an uncertainty can be misleading.
Fit and Cronos, with their possibility to repeat several measurements beginning a few seconds after the previous one
and without stopping minutes for cooling and rinsing, offer a double advantage: save time and work with the same laser
conditions.
Automatic measurements mean that there is no need to measure the exposure time and that, for this, no errors are
introduced . The 4 or 8 seconds are decided by the internal clock of FIT and Cronos which start and stop measurement
above a triggering level. The operator can keep the probe a longer time under the laser or even insert it in a running
beam : no measurement errors are made . Readings can be done by a single person rather than the usual two
operators, one at the control unit to open/close the shutter and the other one on the machine to make the
measurement.
The possibility to store and recall the last measurement value helps in many industrial works, where hurry and multi-
task activities may distract laser operators.
Accuracy and a high degree of repeatability of measurements are what is needed by several medical applications to
know the exact power delivered to a patient. The Fit series has performances equal to power meters so that FIT
probes can be a powerful substitute whether there no other needs, like long term monitoring. At a fraction of power
meters cost.

Laser Alignment
Verification if maximum power has been reached after laser tweaking can be done in 8 sec with Cronos or 4 sec with
FIT. This measurement is very useful as a crosscheck with laser internal power monitor.

Laser Power Monitoring
Periodical verification of real laser output can be done with laser probes, in particular if there are doubts on effective
delivered power . A practical case is when the laser internal monitor displays a value, but the application is not running
properly.

Monitoring of complete beam delivery systems at the workplace
A monitoring of the complete beam line, down to the workplace, can explain why cutting, welding, etc do not perform
well. Cronos and Fit can easily show discrepancies with the internal laser monitor, indicate that there may be damaged
components on the beam line or power losses due to misalignments.

Verification of Damaged or Dirty Components
Locating damaged optical components can be done easily by making a reading before and a reading after the
component itself. Optical components in good shape never lose more than a very few percent of laser power. Major
losses can be ascribed to damages or dirt ; in any case changing the optics or clean it will save future troubles and
costs.
FIT and Cronos probes are ideally suited for this kind of verification since their reliable measurements permit to trust the
readings and the possibility to make another measurement, a few seconds after the first one , is practically independent
from laser fluctuations.

Fast monitoring of marking and micro-welding systems
Low and mid power lasers can be efficiently monitored by the FIT series. The 1% repeatability and high resolution
(10mw on the 50W model) of those probes, make their measurements the reliable references for setting application
parameters or for periodical verification.

Fast monitoring of medical lasers
Periodical monitoring of CW medical lasers (CO2, Yag, Argon etc) can be quickly done (4 sec) with highly reliable and
precise FIT probes. Verification of losses within articulated arms, breakings of fiber tips, damages on focusing optics or
handles are immediately detectable thanks to the high level of repeatability and high resolution of those probes.
