High-power Yb-fiber femtosecond comb
Carrier-envelope-phase (CEP) stabilized lasers have been widely used in precision spectroscopy,coherent laser ranging and optical frequency metrology.Mode-locked fiber lasers could be well controlled as promising compact and stable optical frequency combs,and high-power amplification with large-mode-area double-clad photonic crystal fibers has power-scaled fiber-based frequency combs up to hundreds of watts.In order to stabilize CEP of the high-power lasers,either a phase servo loop or a difference-frequency-generation scheme could be used.However,the former suffers from its limited feedback bandwidth and negative side effects on laser oscillators,while the latter had a zero offset frequency seriously influenced by increased 1/f noise and other low frequency noises.
