Paper Abstract

Crystalline materials utilized as elements of constructional and power optics in up-to-date instrument making, undergo the action of rather severe heat loads. Developed in the present paper are earlier investigations of the peculiarities of IR-absorption and damage of transparent crystalline CdS and ZnSe materials under the action of CO2-laser radiation. Samples with different stoichiometry and crystallographic orientation cut out of crystalline boules grown by the vertical Bridgman method, were studied. The activation energy of free carriers in the samples was determined while measuring the temperature dependences of electrical resistance. The temperature dependences of IR- absorption were measured by the method of laser calorimetry within 285...750 K temperature range. Peculiarities of optical damage were investigated at the same temperatures. The thermal behavior and peculiarities of the damage pattern of the crystal structure are revealed by microscopy method. The obtained experimental data are discussed and compared with those presented by other authors.
