Plasmonic Saturable Absorbers [PDF]

Advanced Photonics Research, 2021
Plasmonic materials are able to spatially confine light to a nanometer scale far smaller than the diffraction limit, resulting in drastically enhanced electrical field strength and stimulating applications in nonlinear optics, energy, and biomedicine. Resonant excitation of plasmonic nanostructures by ultrafast pulses results in a subpicosecond‐scale ...

Solitons in ultrafast semiconductor lasers with saturable absorber. [PDF]

Nanophotonics
Abstract We describe structure localization and dissipative solitons in a semiconductor laser with a saturable absorber exhibiting gain/absorption recovery times shorter than the photon lifetime. Under assumptions compatible with QCL characteristics and graphene‐based absorbers, we study the existence and stability of solitons, along ...

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.
