摘　　要：报道了一种高峰值功率、窄线宽、高光束质量的主动调Q脉冲固体激光器,具有体积小、结构紧凑、环境适应性强等优点。采用LD侧面空间补偿泵浦、升压式RTP晶体电光调Q、利用布拉格体光栅VBG压窄线宽等技术。在工作频率20 Hz时,获得了脉冲宽度10 ns,单脉冲能量200 mJ,光束发散角2 mrad,在室温25 ℃时,中心波长1064 nm,中心波长漂移量≤0.05 nm,线宽(半高宽)≤0.1 nm的激光输出。An active q-switched solid-state laser with peak power,narrow linewidth and high beam quality is reported in this paper. It has the advantages of small size,compact structure and strong environmental adaptability. LD side-pumping and space-compensating,active RTP Q-switched,volume Brag grating technologies are used in the laser. At the working frequency of 20 Hz,the obtained pulse width is 10 ns,the single-pulse energy is 200 mJ,and the beam divergence angle is 2 mrad. At room temperature 25 ℃,the laser of center wavelength of 1064 nm,central wavelength drift≤0.05 nm,Δλ≤0.1 nm is obtained.
