CrZnS&CrZnSe

CrZnS and CrZnSe laser crystals typically do not exhibit excited-state absorption or upconversion. They possess an extremely broad absorption band, a large emission cross-section, excellent fluorescence quantum efficiency at room temperature, an ultra-wide emission bandwidth, as well as good chemical and mechanical properties. These characteristics make CrZnS & CrZnSe laser crystals excellent sources for efficient and powerful tunable mid-infrared lasers. Since the mid-infrared region corresponds to the atmospheric window, CrZnS & CrZnSe laser crystals hold significant potential for applications in optical communication, pollution gas detection, industrial combustion product testing, and other fields.
