    Cr Znse Laser Material No Excited State Absorption Upper Level Conversion Broad


    Cr: ZnSe laser crystal has the advantages of normally no excited state absorption and upper level conversion, an extremely broad absorption band and large emission cross-section, superb fluorescence quantum efficiency at room temperature and extra broad emission width as well as good chemical and mechanical properties, which make it become an excellent source of efficient and powerful tunable mid infrared laser. Because of mid infrared wavelength band is the window of atmosphere, the Cr: ZnSe laser crystal has important application prospect in the field of photo-communication, pollution gas detection, industrial combustion product test and so on.
