摘要	To achieve stable and efficient amplification of seed laser, we report on a regenerative amplifier based on chirped pulse amplification and thin-disk technology, providing an average output power of 201.4 W at a repetition rate of 50 kHz before being compressed. A closed-loop control system is used to overcome the negative effects of air convection and thermal effects. The regenerative amplifier has a pulse duration of 1.28 ns, pulse amplitude stability of RMS = 2.78 %, spectrum bandwidth of 2.5 nm, and center wavelength of 1031.7 nm. The pulse duration can be theoretically compressed to 591 fs. The output power fluctuation of RMS = 0.51 % is delivered in an excellent output beam characterized by Mx2 = 1.08 and My2 = 1.01, and the optical-to-optical efficiency is 20.9 %. According to the experiment results, the regenerative amplifier proposed in this study is a perfect pre-amplification unit for amplifiers used in the chirped pulse amplification approach because it can steadily produce a chirped laser output with high average power. © 2023
