Dissipative Rogue Waves Among Noise-Like Pulses in a Tm Fiber Laser Mode Locked by a Monolayer MoS2 Saturable Absorber

Abstract

We report on the experimental and numerical investigations of dissipative rogue waves (DRWs) among noise-like pulses, in a thulium-doped fiber laser mode locked by a monolayer MoS2 saturable absorber. By increasing the pumping power or weakening the effective cavity spectral filtering, the statistics distributions of the pulse events deviate from the Gaussian statistics to the L-shaped distributions with long tail, accompanied by the increase of the DRWs proportion. Our observations reveal the dissipat-ive nature of rogue waves in dissipative systems.
