【摘要】 以LD泵浦的三明治腔结构的Nd :YVO4 全固体绿光激光器为例 ,从理论上分析了激光光束的发散角与激光晶体端面与光轴垂面的平行度误差之间的关系 ,并通过实验进行检验 ,结果表明 ,利用这种方法可以方便的确定出激光晶体端面与光轴垂面的平行度误差的允许值 ,定量的对激光工作物质的粘接质量进行检验 ,极大的提高了激光器批量生产的效率。更多还原

【Abstract】 By taking the LD-pumped all-solid-state Nd:YVO 4 gree n laser with a sandwich resonator for example, the relationship between far-field scattering angle and the error of the laser crystal with the vertical plane of t he optical axis was studied. The result shown that this method can check the pas te quality of the laser crystal by quantity and can raise the productive efficie ncy of laser products greatly.更多还原
