Wave-breaking-free passively mode-locked fiber laser using a hybrid regime of oscillation

摘要

We demonstrate the possibility of generating wave-breaking-free optical pulses from a mode-locked fiber ring laser coupled to a long passive resonator. By adjusting the delay line length to match the temporal separation of two consecutive spiking pulses, we have successfully obtained large stable pulses in the microsecond range for any available pump power. Our experimental results demonstrate a new method for energy scaling in passively mode-locked fiber lasers.
