加长棒脉冲钕玻璃激光器的阈值、效率实验研究

Experimental stady of threshold and efficiency On Nd : glass pulsed lasers with tlongated rod

本文从实验方面研究了加长激光棒使其长于椭圆泵浦腔（灯弧长）时，对脉冲钕玻璃激光器输出性能的影响。实验结果发现：在相同条件下，激光棒适当长于椭圆泵浦腔（灯弧长），与棒和椭圆泵浦腔（灯弧长）相等时相比，能降低泵浦阈值、提高输出效率。

This article descvihed the experimental seady of influence upon the outpot pronerties of Nd:glass pulsed lasers in which the laser rod is longer then the longer of the ecliplical cavity. The resuls show that , ander some conditions , their laser threshold is lower and efficiency higher than that of equal-lengen to the cavi-ty.
