Advanced laser material processing of steel and silicon (Conference Presentation)
Author(s): Thomas Kiedrowski

Paper Abstract

A main field of application for USP lasers is the fabrication of high-precision microstructures by ablation of bulk material. In the last 10 years, the output power of USP laser systems increased from around 10 W to several 100 W. This enables the increase of productivity of USP laser ablation processes by more than one order of magnitude. So far there is a leak of appropriate strategies and optical system to overcome limits based on heat accumulation. In this contribution, ablation strategies for steel and silicon by using far more than 100 W is deduced and presented.
