Abstract

Especially for micro machining lasers have opened new possibilities which were not accessible by traditional mechanical processes (e.g. intravolume glass marking). For many applications the raw Gaussian laser beam profiles are not optimal adapted for material processing. Therefore optimized beam profiles like those with homogeneous intensity (so called Top Hat) or with ring shape are often desired to enhance process efficiency and quality.
