The FFC-100 from Vescent Photonics is a fully stabilized octave-spanning frequency comb with precise control over ƒrep, ƒopt, and 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.
Designed for ease of use and performance, the MLL-100’s combination of touch screen interface and rotary knob input makes for simple set up and control. Modulation and control of the pump power as well as fast (via PZT) and slow (via temperature) tuning of the repetition rate makes the MLL-100 ideal as the engine for your frequency comb development. The slow integrator controlling the precise temperature set point allows long-term repetition rate locking when combined with the fast PZT loop.
The Menhir-1550 provides control capability over the repetition rate and carrier envelope offset and so it can serve as the engine for a high-repetition rate frequency comb.
