FIELD: formation of preset images inside the transparent solid materials. SUBSTANCE: the method consists in the fact that a three-dimensional frame model of the image surface is constructed at determination of the co-ordinates of points, then the sections of the image surface with a different gradation of gray color are determined, and the device for formation of the preset image inside the solid material by means of a pulsed laser beam has a multimode laser with a resonator in the form of crossed prismatic reflectors. EFFECT: enhanced quality of image. 2 cl, 8 dwg
