摘要
Abstract
This paper reports on a room-temperature Yb:YAG rod laser with high power and high beam quality.The oscillator utilizes a moderately doped Yb:YAG rod crystal(Yb3+2.0 at atomic fraction of%)and employs quasi-continuous-wave end-pumping.At a repetition rate of 100 Hz,it achieved a 22 W linearly polarized laser output,with a slope efficiency of 53.5%and an optical-to-optical efficiency of 47.4%,while maintaining a beam quality of M2=1.22.Using acousto-optic Q-switching,the laser produced a 20.8 W pulse output with an energy of 9.9 mJ and a beam quality of M2=1.39,demonstrating the laser's capability for high-repetition-rate Q-switched pulse output.关键词
