| 摘 要： | 从泵浦光与腔模的空间匹配函数出发，讨论了泵浦光的发散角、焦点位置等因素对激光系统效率的影响。发现在旁轴近似下，匹配函数的最大值随泉浦光发散角的增大而增大，在考虑到像散的影响后，得到泵浦光发散角的参考值。

| Abstract: | ased on the matching function of pumping light and mode lasing, the effectsof some parameters, such as the divergence angle and focus position of pumping light, on the efficiency are investigated. At paraxial approximation the maximum of the matching function is increasing with increased divergence angle. For different brightness of pumping light, the optimum value of the angle is obtained. |

| Keywords: | longitudinally pumping paraxial approximate matching function |
