CLaser develops a new Q-Switch crystal Cr:ZnSe, for 1.4-2.2um application. It is very good for eye-safe laser systems.
Cr doping of commercial ZnSe was achieved through a thermal diffusion process employing CrSe powder as the dopant source. All samples exhibited the characteristic spectral features of Cr2+-doped II–VI materials with strong IR absorption bands between 1.4um and 2.2um and broad emission spectra from 2000 to 3400 nm. The room-temperature decay times were measured to be 5–6 μs for Cr:ZnSe. The emission lifetime of Cr2+ ions decreased by a factor of two for Cr concentrations of 2.6×1019 cm−3 for Cr:ZnSe.
