Abstract: A method of laser processing of an object (5) by subjecting its surface to laser radiation beams (1) directed on the processed areas (2) of a desired configuration, where three-dimensional phase modulation of the laser radiation beams (1) is effected depending on the desired configuration of the processed area (2) and on a predetermined distribution of the intensity, with simultaneous rotation. A device for implementation of the method comprises a laser radiation source (8) on the optical axis of which is located an optical system (12) intended to deliver the laser radiation to the object (5) and including at least one computer optics phase element (COE) (3) shaped as a reflecting or transparent plate with a microrelief surface structure dependent on the configuration of the processed area (2), on the distribution of laser radiation intensity and its wave-length (lambda), the protrusions (14) of the relief being of a height (h) changing in the direction from the base (a) to the top (b) within a range of values from 0 to lambda/2 for the reflecting plate and from 0 to lambda(n-1) for the transparent plate, where n is the refractive index.
