The FFC-100 from Vescent Photonics is a fully stabilized octave-spanning frequency comb with precise control over the repetition rate (ƒ_rep), optical reference (ƒ_opt), and the carrier envelope offset frequency (ƒ_CEO). 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 ƒ_CEO 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 ƒ_CEO 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.
