摘　　要：探讨了利用半共焦腔的“反演”特性及放电区增益分布特性以及调节平面高反膜红外输出耦合窗口来获得不同的对称性、均匀性良好的激光输出花样。Based on the “inversion” of the half confocal cavity and the curve of gain distribution in the discharge zone,the various laser output patterns can be acquired by adjusting an infra red coupling mirror coated with high reflective film. The output pattern is uniform and symmetrical. The result of expriment is in accordance with theory.
