用空心波导控制染料激光器输出横模的实验分析

Optical absorption cross section measurement of the uranium atom by the pulse laser saturation fluorescence

本文报道了一种控制染料激光器输出横模的方法－在染料激光器谐振腔内加入一段圆形空心玻璃波导。文中对实验结果进行了详细的分析，从而证明了这种方法对控制激光横模、提高光束质量有很好的效果。

In this paper,we introduce optical absorption cross section of the uranium atomic level (0～16900cm -1 )and describe principle and result of the experiment.The result of the experiment is in concordance with the foreign's.
