摘要：

ZnSe:Co2+ crystals were grown by the Bridgeman technique. Optical absorption measurements showed non-uniform distribution of Co2+ ions along the as-grown crystals. Using Kann formula the distribution coefficient of Co2+ ions between crystal and melt was estimated to be 0.5. Transmission dependence on laser power at lambda = 1535 nm was investigated for different Co2+ ions concentration. Maximal final transmission was found for ZnSe samples containing 1.6 x 10(19) cm(-3) of Co2+ ions. Obtained ZnSe:Co2+ samples were used as saturable absorbers to generate giant-pulse eye-safe laser radiation. KIGRE QE-7S rod placed in resonator cavity was used as active element.
