10-Watt, pure continuous-wave, polycrystalline Cr2+: ZnS laser

Academic Article

Abstract

  • We demonstrate, for the first time, 10 W, Er-fiber laser pumped, pure CW, thermally diffusion doped, polycrystalline Cr2+:ZnS laser operating at 2380 nm. We also show Littrow-grating, "single-knob", wavelength tuning of the laser spanning 1940-2780 nm spectral range with the maximum output power of 7.4 W near the central wavelength of 2400 nm and above 2 W over 1970-2760 nm wavelength range. The laser performs with 40% real optical- and 43% slope efficiency, and shows no output power roll-off up to the highest available incident pump power of 27 W. © 2009 Optical Society of America.
