摘　　要：报道了激光二极管(LD)抽运的国产Yb:YAG陶瓷高功率被动调Q激光器。实验中使用半导体可饱和吸收镜(SESAM)作为调Q元件,在6.3 W的吸收抽运功率下得到了被动调Q激光脉冲输出。调Q激光脉冲的最大平均输出功率为1.24 W,脉冲宽度为2.93μs,重复频率为31kHz,单脉冲能量为40μJ。国产Yb:YAG陶瓷的连续激光和调Q激光的性能研究表明,高质量国产Yb:YAG陶瓷在高功率短脉冲固体激光器方面有潜在的应用价值。A high power passively Q-switched laser of diode-pumped domestic Yb： YAG ceramic is reported in this paper. In the experiment, a semiconductor saturable absorber mirror （SESAM） is used as the Q-switching component, and the passively Q-switched laser pulse output is obtained under the absorbed pump power of 6.3 W. The maximum average output power of the Q-switched laser pulses is 1.24 W, the pulses＇ duration is 2.93 μs, the repetition rate is 31 kHz, and the single pulse energy is 40 μJ. By studying the performance of the domestic Yb： YAG ceramics under continuous and Q-switched laser, the potential applications of domestic high-quality Yb： YAG ceramics in hi,h-Dower short-pulse solid-state lasers are revealed.
