Abstract

The aim of the invention is to machine a material by application of non-linear radiation. The aim is achieved by modifying the laser radiation emitted by a laser beam source with the aid of a polarization modulator in such a way that laser radiation focused into the material is polarized in a linear fashion, the direction of polarization varying across the cross section of the beam.
