摘要

We report a regime of the loose soliton bunch in an erbium-doped passively mode-locked fiber laser.In this state,every soliton bunch consists of multiple pulses.The amount of multiple pulses inside the soliton bunch increase as the pump power rises.Moreover,the temporal average pulse-to-pulse separation decreases in general with the increase of the pump power.Further,the spatial-temporal sequences based on the dispersive Fourier transformation technique show that pulse-to-pulse interactions and time jitter can result in pulse forking inside the soliton bunch.Finally,we theoretically demonstrate the soliton btmch with different pulse-to-pulse separations.
