摘　　要：介绍了氙灯抽运的片状固体热容激光器的研究进展。基于大口径片状介质,设计了布鲁斯特角和V形有源镜两种构形激光器,实验研究了两种激光器的静态损耗和增益能力,并对两种构形激光器输出能力进行了测量,获得了最大单脉冲能量达47 J,输出平均功率近1 kW的实验结果。探讨了片状构形向更高平均功率发展的技术途径,并通过实验验证了纵向定标放大的可行性。得出了V形有源镜构形激光器更适合向高平均功率发展的结论。Progress of a flashlamp-pumped solid-state heat capacity slab laser is presented.Based on large-aperture Nd:YAG slabs,a Brewster-angle and V-shaped active mirror configuration of laser was designed respectively.The passive loss and gain performances were measured experimentally for these two kinds of lasers.An output of 47 J in pulsed operation,and average power about 1kW was obtained experimentally.Based on power scaling experiments,a high–average-power approach with such active-mirror configuration was also discussed.
