The FFC-100 from Vescent Photonics is a fully stabilized octave-spanning frequency comb with precise control over the repetition rate (ƒrep), optical reference (ƒopt), and the carrier envelope offset frequency (ƒCEO). It is built around the Vescent MLL-100 Mode-Locked Laser, a stand-alone erbium-based femtosecond MOPA. A highly non-linear fiber broadens the spectrum and our unique ƒCEO lock detection reduces the size, weight, and power of the system. The complete FFC-100 frequency comb is designed and built to ensure stable, low-phase noise operation with Allan Deviations supporting the next generation of optical atomic clocks.
The FFC-100 was designed for low SWaP and turn-key, stable operation: A single 2U 19” rack mount chassis contains the oscillator, amplifier, pump lasers, supercontinuum generation module, and ƒCEO detection and lock as well as the control electronics.
The simple oscillator mode locks at startup every time and the innovative passive SESAM mode-locker is specially designed for a robust, long life. Our unique oscillator design also makes it easy to precisely factory match the repetition rate of two (or more) FFC-100 combs for multi-comb spectroscopy experiments.

1 Does not include the SLICE-FPGA controller, which is sold separately.
2 Allan Deviation from zero-dead-time L counter with 1s gate time.
3 Depends on user-supplied optical reference. Data given for 1 kHz 1560 nm reference laser with >0.1 mW input power when phase locked with a SLICE-FPGA.
4 Allows access to a slow servo correction mode that automatically changes oscillator cavity temperature so that the PZT is centered in its operating range.
