报告摘要:

    The presentation is devoted to overview of study ofsolid-state lasers based on single-crystalline or polycrystalline chalcogenidesZnSe and CdSe doped by Cr2+ ions. Gain switched laser operation atwavelengths of 2.3-3 μm under 2-μm laser pumping was studied.

    Efficient gain-switched laser operation at 2.3-2.7 µmwas achieved in polycrystalline Cr2+:ZnSe slabs (with rectangular orzig-zag optical-path configurations) pumped at 2.1 µm by the pulsed Ho3+:YAGlaser. Laser oscillator based on Cr2+:CdSe single crystal pumped byradiation of Tm3+:Lu2O3-ceramic laser wascreated and investigated. Repetitively-pulsed oscillations at the wavelength of2.92 μm with bandwidth of 80 nm were demonstrated.Efficientgain-switched Cr2+:CdSe single-crystal laser operating around 3 µmand pumped by a 2.09-µm repetitively-pulsed Ho3+:YAG laser wascreated..
