A continuous-wave Fe{sup 2+}:ZnSe laser

A continuous-wave oscillation is obtained for the first time in a Fe{sup 2+}:ZnSe laser. The laser wavelength was in the range from 4.04 to 4.08 {mu}m. A liquid-nitrogen-cooled active element was pumped by a Cr{sup 2+}:CdSe laser at 2.97 {mu}m. The maximum output power of the laser was 160 mW with t...

Zusammenfassung:	A continuous-wave oscillation is obtained for the first time in a Fe{sup 2+}:ZnSe laser. The laser wavelength was in the range from 4.04 to 4.08 {mu}m. A liquid-nitrogen-cooled active element was pumped by a Cr{sup 2+}:CdSe laser at 2.97 {mu}m. The maximum output power of the laser was 160 mW with the 56% slope efficiency. The minimum absorbed pump power threshold was 18 mW. The intrinsic losses in the Fe{sup 2+}:ZnSe crystal did not exceed 0.024 cm{sup -1} during lasing. (lasers. amplifiers)
