FFC-CM Frequency Comb Optical Module
FFC-CM optical module for octave-spanning, fully stabilized fiber frequency comb
The FFC-CM incorporates all the requisite optical elements to build a fully stabilized octave-spanning frequency comb: a temperature-stabilized oscillator, amplifier, supercontinuum generation, and 1ƒ-to-2ƒ interferometer, as well as high-bandwidth repetition rate control. Pair it with diode pumping and servo electronics for stable, low-phase noise operation with Allan Deviations supporting the next generation of optical atomic clocks.
Compact dimensions, low power consumption, and a robust design ready the FFC-CM to deploy in the field. 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) combs for multi-comb spectroscopy experiments.
