Abstract
We report the development of a continuous-wave, room-temperature Cr2+ ZnS laser that is compact and tunable over 700 nm. The laser is pumped by a diode-pumped Er-fiber laser and generates 0.7 W of linearly polarized radiation at 2.35µm , at up to 40% slope efficiency. Cr2+ ZnS directly diode-pumped at 1.6µm yields polarized radiation that is tunable over 400 nm at up to 25 mW of output power. A comparison of Cr2+ ZnS with Cr ZnSe (70 mW, 350 nm) in a similar setup is given. As opposed to Cr ZnSe, the Cr ZnS laser is intrinsically polarized. Finally, we observe sensitization of the output radiation by a few milliwatts of the visible (470–500-nm) and near-infrared (740–770-nm) radiation.
