Demonstrations of cw lasing in Cr2+:ZnSe poly-crystal are reported.The laser consists of a 1.7-mm-thick Cr2+:ZnSe poly-crystal disc pumped by a Tm-silica double-clad fibre laser at 2050nm.Using a concave highreflection mirror with a radius of curvature of 500mm as the rear mirror,the laser delivers up to 1030mW of radiation around 2.367μm.
