110 W All Fiber Actively Q-Switched Thulium-Doped Fiber Laser
IEEE Photonics Journal, 2015 We report a 100-W-level, repetition rate and pulsewidth tunable, all-fiber, thulium-doped master oscillator power amplifier system. The master oscillator was actively Q-switched by a fiber-coupled acousto-optic modulator.

A Passively Q-Switched Holmium-Doped Fiber Laser with Graphene Oxide at 2058 nm
Applied Sciences, 2021 This study reports a Q-switching-based, 2058-nm holmium (Ho) fiber laser incorporating a saturable absorber (SA) based on graphene oxide (GO). The SA was prepared with a side-polished fiber, while GO particles were deposited onto the fiber-polished ...

Ultrafast thulium-doped fiber laser mode-locked by antimonides
Optics Express, 2021 We report, for the first time, the nonlinear absorption at the 2 µm waveband of three Sb-related materials including two Sb compounds, GaSb and InSb, and one Sb alloy, Ge8Sb92. These saturable absorbers (SAs) were coated on tapered single mode fibers by the magnetron-sputtering deposition method.
