横流CO_2激光器的折叠式谐振腔研究

Study on folded resonator for transverse flow CO 2 Laser

在横流ＣＯ２激光器中采用折叠式谐振腔，不仅能改善光束质量，而且能提高转换效率。文章对折叠式谐振腔的折数确定，转折镜的选择，谐振腔的总体结构进行了分析研究，并设计了一种七折光学折叠腔，在大功率横流激光器上取得了良好的实验效果。

The folded resonator used in transverse flow CO 2 laser improves quality of laser beam and increases efficiency.This paper discusses about the fold number of folded resonator,the choice of folded reflector and the whole structure of resonator.In experiment 1052W TEM 00 mode laser output is obtained with seven fold resonator.
