Monotonous increase of ZnO single crystal electrical conductivity up to 250 times was observed after irradiation by Nd:YAG laser. This effect is explained by increase of the Zn interstitial atoms’ concentration at the irradiated surface of the crystal. At the same time, the improvement of ZnO crystal quality by laser intensity up to 3.2 MW/cm2 takes place. The further increase of laser intensity led to emergence of cracks on the irradiated surface of the crystal and the dramatic decrease of the total photoluminescence intensity, especially, around the cracks. At the laser intensity 290 MW/cm2 Zn nanoparticles were formed.
