Abstract
The invention relates to a process for the control of the laser beam intensity distribution for the processing of component surfaces by means of laser radiation, whereby conventional mirrors and mirror systems are used to shape the laser beam and laser beam shaping takes place on the basis of sinusoidal, harmonic beam oscillation as a control function for the mirror or the mirror system by means of at least one galvanoscanner. According to the process provided by this invention, the intensity distribution produced during laser beam shaping on the basis of sinusoidal beam oscillation on a component surface is adjusted independently of the selected shape and size of the scanned surface area without any action having to be taken on the laser used.
