Abstract: Transmission of a polycrystalline Fe²⁺ : ZnSe sample during irradiation by a pulsed Er³⁺ : YAG laser with a wavelength of 2940 nm is measured at low and room temperatures. It is found that the sample in a strong field (energy density 1.3 J cm^-2, laser pulse duration 320 ns, peak intensity 4.1 MW cm^-2) is bleached almost completely at both low and room temperatures. The temperature dependence of transmission is measured in the range of 105 – 273 K in weak and strong fields.

Keywords: Fe²⁺ : ZnSe, nonlinear transmission, low temperature.
