摘　　要： 为了输出高功率、高光束质量的脉冲激光以及制备高质量微孔，对平凸非稳腔结构进行了理论分析，给出了腔参数变化曲线．设计出了高功率、高光束质量的平凸非稳腔灯泵浦脉冲Nd：YAG调Q激光器．激光脉冲能量为500mJ，峰值功率达到5MW，光束参数积优于4．2mm·mrad．分别在0．04—0．07mm厚度金属碳钢及1mm厚度非金属陶瓷上进行了微孔打孔实验，得到了百微米微孔． The purpose of this paper is researching about high-power and high beam quality laser as well as the experiment of the high-quality micro-hole. The theoretical analysis of the plane-convex unstable laser resonator structure is introduced. The parameter about resonator is analyzed. The high-power and high beam quality pulsed Nd： YAG laser with the plane-convex unstable laser resonator pumped by lamp is designed. The output of laser pulse energy is 500 mJ; the peak power is 5 MW. The beam parameter product （BPP） is superior to 4.2 ram. mrad. Using the laser for drilling processing experiment on metal （ steel material） with different thickness from 0.04 mm to 0.07 mm and non-metal （ceramics material） with 1 mm thickness is achieved.
