150 mW Tb3+doped chalcogenide glass fiber laser emitting at λ > 5 μm

The paper describes terbium-doped chalcogenide glass fiber lasers emitting up to 150 mW at 5.1-5.4 mu m under CW pumping by a thulium 1.908 mu m fiber laser. Attention is drawn to the temporal dynamics of their radiation and to its dependence on the doping level.

Automated summary

The paper discusses the characteristics of terbium-doped chalcogenide glass fiber lasers which can emit up to 150 mW of power at 5.1-5.4 μm wavelength when pumped by a thulium 1.908 μm fiber laser. The temporal dynamics of the laser's radiation and its dependence on the doping level are emphasized.
