Abstract

The possibility to increase the radiation hardness of Cd 0.9 Zn 0.1 Te crystal using pulsed Nd:YAG laser radiation was shown. Estimation of the crystalline lattice defects before and after irradiation by γ-ray using photoluminescence method in the experiments was applied. Experimental results showed the increase of the radiation hardness of CdZnTe crystal after irradiation by the laser at intensity 1.20–1.80 MW/cm 2 .
