New possibilities for efficient laser surface treatment by diode-pumped kW-class lasers

Abstract

The newly developed so call multy-slab laser at premise of the research centre HiLASE is already recognized as a potential new source for efficient laser surface treatments. Once the system is in full operation the pulses of up to 100J with pulse duration of 2-10 ns will be delivered with repetition rate of 10 Hz. In this paper the status of this new laser system is presented. Additionally the design of a new experimental station for laser surface treatments is also discussed. According to preliminary plans the station will be ready for first experiments in 2016.
