Full phase stabilization of a Yb:fiber femtosecond frequency comb via high-bandwidth transducers [PDF]
, 2012 We present full phase stabilization of an amplified Yb:fiber femtosecond frequency comb using an intra-cavity electro-optic modulator and an acousto-optic modulator. These transducers provide high servo bandwidths of 580 kHz and 250 kHz for frep and fceo,

Low-noise Yb:CALGO optical frequency comb
Optics Express, 2021 We report on a compact optical frequency comb, operating in the wavelength range from 670 to 1500 nm, based on diode-pumped low-noise femtosecond Yb:CALGO amplified laser system. Both the carrier-envelope offset and repetition rate are phase-locked to reference synthesizers. A full characterization of the frequency comb, in terms of frequency stability,

Optical Frequency Comb Generation based on Erbium Fiber Lasers
Nanophotonics, 2016 Optical frequency combs have revolutionized optical frequency metrology and are being actively investigated in a number of applications outside of pure optical frequency metrology. For reasons of cost, robustness, performance, and flexibility, the erbium

Optical Frequency Combs in Quadratically Nonlinear Resonators [PDF]
Micromachines, 2020 Optical frequency combs are one of the most remarkable inventions in recent decades. Originally conceived as the spectral counterpart of the train of short pulses emitted by mode-locked lasers, frequency combs have also been subsequently generated in continuously pumped microresonators, through third-order parametric processes.
