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，并通过实验获得了与理论相符的结果 In this paper, the use of semi-confocal cavity “inversion” characteristics and discharge area gain distribution characteristics as well as the adjustment of plane high-reflective infrared output coupling window to obtain different symmetry, good uniformity of the laser output pattern, and obtained by experiments and The result of the theory is consistent
