| الوصف: | The influence of free electrons in Fe2+: ZnSe crystals on the nonlinear transmission of high-power laser radiation with a wavelength of 2940 nm at room and low temperatures is experimentally found. Fe2+ : ZnSe samples additionally doped with Al are used. The transmission of an Al : Fe : ZnSe sample with electron conduction in a strong (peak intensity about 4.6 MW cm−2) field is almost the same as in a weak field both at low and room temperatures. The absence of an increase in the transmission of this sample under the action of high-power radiation is explained by increasing absorption saturation intensity of Fe2+ at this wavelength due a decrease in the lifetime of the excited state of Fe2+. The decrease in the lifetime is related to the well-known Auger quenching of impurity luminescence in semiconductors by free electrons. |
