Abstract

Highlights: Five microns chalcogenide glass fiber laser. Terbium laser with 150 mW output. Self Q-switching of terbium fiber laser. Abstract: The paper describes terbium-doped chalcogenide glass fiber lasers emitting up to 150 mW at 5.1–5.4 μm under CW pumping by a thulium 1.908 µm fiber laser. Attention is drawn to the temporal dynamics of their radiation and to its dependence on the doping level.
