Increasing laser processing efficiency using multibeam and tailored beam profiles

Beam shaping optics help to optimise results in laser material processing. By using diffractive beam splitters, multibeam arrays can be generated, leading to higher process speed and therefore lower cost. Process speed can also be increased with tailored beam profiles - for example, top hat profiles, because pulse-to-pulse overlap can be reduced. Furthermore, tailored beam profiles increase the quality of ablation.

The presentation shows typical optical setups for beam shapers and beam splitters, and their integration in existing optical setups. He will also present scribing results of different applications using nano-, pico- and femtosecond lasers.
