In this study, the designing method of multi-beam regenerative amplifiers with the repetitive rate was proposed and demonstrated. To obtain multi-beam regenerative amplifiers with uniform performance, the disparities in output energy, energy stability, and mode size were analyzed, and the detailed optimizing method was presented. With the designs, eight-beam regenerative amplifiers were developed. The output performances of eight-beam regenerative amplifiers were uniform. The output energies were in the range of 25.4–28.8 mJ, and the energy stabilities over two hours were in the range of 2.4%–5.1% (PV) and 0.3%–0.9% (RMS).
