					M-COMB Femtosecond Fiber Laser

Femtosecond Source Engineered for Metrology Applications
New features make the M-Comb an ideal core component of versatile optical frequency comb systems
with improved performance. The three optical output ports can be amplified and by subsequent
frequency conversion the IR and the VIS spectral ranges are simultaneously available for precision
measurements. The high repetition rate entails larger spacing between the comb modes, which
ensures easy and straightforward frequency measurements, and provides higher optical power per
comb mode.

Features and Benefits
• Engineered for ultrahigh stability and ultralow phase noise
• Highest fundamental repetition frequency available on the market
• Truly turn-key operation by self-starting mode-locking mechanism with
  integrated microcontroller ensuring uninterrupted operation
• Temperature stabilized
• Repetition rate 250 MHz
  – tunig range 2.5 MHz, coarsly adjustable with stepper motor
  – fine-tuned and locked with a Piezo
• CEO frequency
  – tunable within the free spectral range of 250 MHz with intracavity wedge
  – stabilized by pump power modulation
