Stimulated soliton pulse formation and its mechanism in a passively mode-locked fibre soliton laser

摘要

We report on the stimulated formation of soliton pulses in a passively mode-lockod fibre soliton laser. We found experimentally that if there are soliton pulses in the cavity, new soliton pulses can be generated one by one with very low pump threshold. We show that the mechanism for the soliton pulse generation is a soliton shaping of dispersive waves in the laser.
