Ultrafast erbium-doped fiber laser using electrodeposition coated MoS2 thin film as saturable absorber

Materials Research Express, 2023
In this work, we have experimentally demonstrated the ultrafast laser in Erbium-doped fiber laser using MoS _2 as saturable absorber. The MoS _2 SA in this work is prepared by bottom-up method.

III-V-on-silicon anti-colliding pulse-type mode-locked laser [PDF]

, 2015
An anti-colliding pulse-type III–V-on-silicon passively mode-locked laser is presented for the first time based on a III–V-on-silicon distributed Bragg reflector as outcoupling mirror implemented partially underneath the III–V saturable absorber. Passive

Controlled Generation of Bright or Dark Solitons in a Fiber Laser by Intracavity Nonlinear Absorber

IEEE Photonics Journal, 2016
We numerically found that an intracavity nonlinear absorber (saturable absorber or reversed saturable absorber) plays a crucial role in the formation of dissipative bright or dark solitons in a fiber laser. The operation of an all-normal-dispersion fiber

Passively Mode-Locked Ytterbium-Doped Fiber Laser Based on Fe₃O₄ Nanosheets Saturable Absorber

Photonics, 2022
Two-dimensional material nanosheets have always been a research hotspot because of their unique structure and properties. We report mode-locked operation in ytterbium-doped fiber laser (YDFL) for the first time by adopting Fe3O4 nanosheets as a saturable

2D Chalcogenide Thin Films for Super-Resolved Laser Structuring [PDF]

EPJ Web of Conferences, 2023
The saturable absorption behaviour associated with chalcogenide thin films has been investigated and optimized using Z-Scan Technique. Huge saturable absorption responses (of the order of 10^-7 m/W) were observed for the Bismuth Selenide thin films ...
