Application of a multilayer Molybdenum Disulfide (MoS_2) thin film as a saturable absorber
was experimentally demonstrated by realizing a stable and robust passive mode-locked …

We report a passively Q-switched and mode-locked erbium-doped fiber laser (EDFL) based
on PtSe_2, a new two-dimensional material, as a saturable absorber (SA). Self-started Q …

Graphene, whose absorbance is approximately independent of wavelength, allows
broadband light–matter interactions with ultrafast responses. The interband optical …

We demonstrate the optical performance of passively mode-locked pulses in erbium-doped
fiber laser incorporating gold-nanoparticles (Au-NPs) as a saturable absorber (SA). Au-NPs …

We demonstrated saturable absorbers (SAs) based on silver nanoparticles (SNPs) by
depositing them on the end facet of the fiber. The SNPs-based SAs showed large …

Over the past decade, Q-switched fiber lasers have drawn extensive attention in nonlinear
frequency conversion, industrial material processing, bioscience, spectroscopy, etc., due to …

We demonstrate the generation of noise-like pulses (NLPs) and soliton rains in a graphene
saturable absorber mode-locked erbium-doped fiber laser. Typical NLPs are obtained at a …
