Abstract
The laser source with high peak power and high beam quality has important application in laser processing and other fields. A fiber laser with repetition of 50 kHz, pulse width of 3.9 ps, and average power of 10.9 mW is used as the seed source. After double-passing two-stage amplifiers, the average output power of 27.65 W with a peak power of 65 MW is obtained. The first stage is an end pumped Nd:YVO4 amplifier, and the second stage is a side pumped Nd:YAG amplifier. The beam quality is well preserved with M2 factor of 1.3 based on the method of spherical-aberration compensation and the optimizing of the beam filling factor.
