The method for control of the parameters of laser radiation based on its recording in the diffuse reflecting screen plane and subsequent digital processing of the recorded image is described. The corresponding algorithm for determining the spatial laser beam parameters is presented and implemented in software. Experimental approbation has been performed using a digital high speed video system and a solid-state pulsed-periodic laser on an alexandrite (Cr3+:BeAl2O4) crystal. The proposed method is compared with standardized method of radiation recording by a matrix photodetector.
