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

80-Gb/s OTDM system analysis of a vertical microcavity-based saturable absorber for the enhancement of pulse pedestal suppression [PDF]

, 2007
In future high-speed optical time-division-multiplexed (OTDM) systems, an important factor that needs to be considered for optical pulse generation schemes is the impact of pulse pedestals on the overall system performance.

Broadband saturable absorption in germanene for mode-locked Yb, Er, and Tm fiber lasers

Nanophotonics, 2022
Passively mode-locked lasers have been widely investigated as one of the effective methods to obtain ultrashort pulses. As an important part of passively mode-locked fiber lasers, the exploration of 2D material-based saturable absorber has become one of ...

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 ...

Passively Q-Switched Er:LuAG Laser at 1.65 μm Using MoS2 and WS2 Saturable Absorbers

IEEE Photonics Journal, 2017
We describe passively Q-switched Er:LuAG laser characteristics at 1.65 μm for the first time, with MoS2 and WS2 as the saturable absorber, respectively. The saturable absorbers were both prepared with the liquid phase exfoliation method.
