Abstract

Regenerative amplifiers based on thin-disk technology have a high-beam quality output laser due to their own excellent thermal management. Conventional thin-disk regenerative amplifiers are usually constructed in a stable resonator design with a long resonator length, which limits the practical application range and further industrialization. We report a compact thin-disk regenerative amplifier with an overall resonator length of less than 2.5 m that enables high-beam-quality laser output. Continuous laser output of 66 W when the resonator is 2.16 m. 59 W of a pulsed laser with a repetition rate of 50 kHz was output at a resonator length of 2.3 m. The thin-disk regenerative amplifier has the potential to output a laser up to 100 mJ while maintaining good beam quality
