摘要: This invention relates to industrial physics and, in particular, to methods of laser treatment. The laser treatment method consists of irradiation of the surface of an object by laser beams directed to treatment zones having a desired shape, wherein laser beams are subjected to spatial phase modulation dictated by the shape of the treatment zone and the prescribed distribution of intensity and are, simultaneously, rotated.A device realizing this method comprises a source of laser radiation with an optical system for delivery of laser radiation to the object, which is positioned on the optical axis of the source and includes at least one phase computer-designed element made as a reflecting or transmitting plate with a micropattern on the surface thereof, which is dependent on the shape of the treatment zone, distribution of laser radiaiton intensity, and its wavelength (.lambda.), the height (h) of the peaks of the micropattern varying, from the base (a) to the top (b), from 0 to .lambda./2 for the reflecting plate and from 0 to .lambda./(n-1) for the transmitting plate, where n is the refractive index of the transmitting plate.
