Abstract

By employing the technique of asynchronous mode locking, we have successfully demonstrated direct generation of stable 10GHz 816fs pulse trains with a supermode-suppression ratio >70dB from a hybrid mode-locked Er-fiber laser. When the modulation frequency deviates from the cavity harmonic frequency by 1540kHz, stable femtosecond soliton pulses are formed. Our results demonstrate that asynchronous mode locking can act as an effective mechanism for achieving a shorter pulse width and for stabilizing high-repetition-rate pulse trains in soliton fiber lasers.
