摘　　要：为了改善Cr4+∶YAG被动调Q激光器的输出稳定性,采用了定向棱镜谐振腔,通过实验得到了以下结果:单脉冲能量稳定度由7. 3%提高到2. 2%,脉宽稳定度由13. 5%提高到6. 5%,频率精度由0. 01%提高到0. 005%,输出脉冲波形稳定光滑。研究表明,采用定向棱镜谐振腔技术的Cr4+∶YAG被动调Q激光器的输出稳定性较原平平腔激光器得到了显著改善。另外还报道了定向棱镜谐振腔技术消除Cr4+∶YAG被动调Q激光器子脉冲的现象。In order to improve the output stability of LD pumpe d Nd∶YAG laser Q-switched by Cr 4+∶YAG,the direc tional prism resonator is used,a single smooth laser pulse has been achieved wi th the energy stability changing from 7.3%~2.2%,pulse-width stability changing from 13.5%~6.5%,repetition rate stability changing from 0.01%~0.005%.The exper imental result shows that compared with the plano-plane resonator,the directio nal prism resonator improves output stability of the laser greatly.It is reporte d for the first time that the directional prism resonator can eliminate the tail -pulse.
