We investigated the use of crystalline coatings as the highly reflective coating of an Yb:YAG thin disk directly bonded onto a silicon carbide heatsink. Compared to commonly used ion-beam-sputtered coatings, it possesses lower optical losses and high

We demonstrated drawbacks of CVBG compressors of picosecond pulses at average power exceeding 50W. Significant reduction of beam quality and peak intensity can be addressed to residual absorption of bulk material and induced Kerr effect.

We report on the characterization of a high-power, chirped volume Bragg grating (CVBG) pulse compressor. It includes measurements of the CVBG’s diffraction efficiency, beam profile, beam quality ( M 2 parameter), pulse spectrum, the CVBG’s temper

Multi-beam micro- and nano-machining of material surfaces has been getting more important because of its great potential to increase production speed of large size laser induced periodic surface structures (LIPSS). Fast and cheap production of engine
