We report room-temperature operation of an all solid-state, continuous-wave Cr2+:ZnSe laser. The laser was pumped by a Tm:YALO laser operating at 1940 nm. Demonstrated Cr:ZnSe laser results include: output power of 380 mW, an absorbed power slope efficiency of 63%, an absorbed power threshold as low as 98 mW, and continuous tunability from 2138 to 2760 nm. All Cr:ZnSe laser crystals were prepared by the diffusion doping technique.
