Abstract

A process for controlling the beam intensity distribution in laser beam surface treatment, comprises using a conventional mirror (system) for beam shaping carried out using the sinusoidal harmonic beam oscillation as control function for the mirror (system) by means of one or more galvano-scanners. The intensity distribution, produced on a component surface during beam shaping, is adjusted independently of the selected shape and size of the scanned surface region, without the need for action on the laser.
