Abstract

The present invention relates to a method and a device for forming the intensity profile of a laser beam, in particular for producing a homogeneous intensity profile. In an embodiment of the present invention, the laser beam can strike an optically addressable spatial light-modular (OASLM), whose local transmission or reflection properties depend in nonlinear fashion on the local illumination intensity.
