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 (M2 parameter), pulse spectrum, the CVBG’s temperature, and the thermal lens. These parameters were monitored for a wide range of input laser powers and with different clamping forces applied on the CVBG. This analysis was performed with a CPA-based Yb:YAG thin-disk laser system operating at a wavelength of 1030 nm, a 92 kHz repetition rate, 2 ps pulse duration, and an average output power after compression of 216 W (270 W uncompressed), which is, to the best of our knowledge, the highest value reported to date using this pulse compression technique.
