    Fiber-coupled Industrial Diode Laser Eras


     Reliability (inception  2003) “$$$’s and *#&%^!!”
        – DPSS is considered technology of the future (“always has
          been, always will be…”)
        – Diode laser investment focused in telecom
        – Unreliable, low brightness bars are only choice


     Telecom-grade (2003  ?) “$/Watt”
        – Telecom migrants disrupt brightness, drive $/Watt
        – Even low-end bars reliably deliver 10,000hrs
        – Reliability and $/Watts begin to de-couple

    What is a Telecom-Grade Diode Laser?

     Operational Excellence and Business Breadth
        – Large, fully-absorbed fab (ISO-9001 a decade ago, now TL-9000)
        – High-volume off-shore assembly


     Technical and Cost Roadmaps, Extensive Track Record
        – Platforms, not just products


     Predictable, sustained performance
        – Rigorous NPI, PCN and PDN processes
        – Reliability understanding surpasses the qualification report


     … Confidence and Transparency for the Customer!

    Telecom 980nm pump lasers since 1993…

     90mW 980nm pumps assembled in Boston sold for $7000

     Five chips, several packages, one transfer to China later…
          – 500mW 980nm pumps sell well below $1000
          – 90mW 980nm pumps cost $300
          – and 980nm pump vendors are (again) profitable




     Over 13yrs, innovation and focused cost-reduction realized
          – 21% annual price reduction for 90mW part
          – 15% annual power increase for 980nm pumps
          – 26% annual $/mW price reduction to the market

                                           Commercially available fiber-coupled power
                                           from 100um 9xx nm fiber laser pump diodes

                              10.0
                 Power (W)




                               1.0

                                                14% average annual
                                                  power increase

                                                         Year of Introduction

    Annual 17.5% (red) power increases enabling 26% annual $/Watt erosion
    predicts a reliable 35W fiber-coupled diode will sell for $70 in 2016…!!

    Third Industrial Diode Era - Efficiency

 Diode Efficiency (2005  ?) “still $/Watt”
     – reliable power is limited by waste heat

                                                 32 Watts




 For diodes to progress, efficiency must increase

     Diodes and Fiber – Disrupting the Laser Industry

      Fiber is a new paradigm
           –     Fiber-based Laser        SS/Gas Lasers
           –     Modular, spliced         Delicate alignments
           –     Service free             Disposables
           –     High efficiency (25+%)   Low efficiency (few to 10%)
           –     High brightness          Inferior brightness




      Direct Diode systems are just another fiber laser
      Solid-state (classic) lasers are adopting fiber

     Summary


      Pump diode lasers are mature, reliable
           – Telecom-grade diodes soon to be
             ubiquitous in the industrial laser industry


      Fiber lasers are merely the most
       important variety of fiber laser
