Abstract	The present paper deals with the laser ablation in CdZnTe crystal irradiated by pulsed infrared laser. Twovalues of threshold intensities of the laser ablation were determined, namely of about 8.5 and 6.2 MW/cm2for the incident and the rear surfaces, correspondingly. Lower intensity of the laser ablation for the rearsurface is explained by thermal self-focusing of the laser beam in the CdZnTe crystal due to heating of Teinclusions with a following hydrodynamic expansion.
