Generation of trapezoidal envelope pulses and soliton rains from passively mode-locked fiber laser with MoS2 saturable absorber on microfiber

We report the generation of trapezoidal envelope pulses and soliton rains in an erbium-doped fiber laser with an MoS2-deposited microfiber saturable absorber. The pulse duration of the trapezoidal envelope pulses increases from 7 to 95 ns with the increment of the pump power. The maximum intracavity...

Description
Summary:We report the generation of trapezoidal envelope pulses and soliton rains in an erbium-doped fiber laser with an MoS2-deposited microfiber saturable absorber. The pulse duration of the trapezoidal envelope pulses increases from 7 to 95 ns with the increment of the pump power. The maximum intracavity pulse energy is as high as 34 nJ. At a low pump power, the proposed laser can be switched to the soliton-rains regime by properly changing the polarization states. The microfiber-based MoS2 all-fiber laser can serve as an optical source with improved pulse energy for potential applications in nonlinear dynamics.
