Increased radiation hardness of CdZnTe by laser radiation

The aim of this work is to study the possibility to increase the radiation hardness of Cd 0.9 Zn 0.1 Te crystal using laser radiation. Pulsed Nd:YAG laser for this aim was used. 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 laser at intensity 1.20–1.80 MW/cm 2 .
