摘　　要：提出了边界波具有π跃变性质的假说，作为惠更斯—菲涅耳原理的补充。根据该假说，在腔外和腔内实现了一系列新光束。重要的是，实现了等效光束质量因子小于１的新光束ＣＯ２激光器。这可看作是可控非线性自聚焦的结果。A new suggestion that there is a phase jump of in the boundary wave is put forward in this paper.This suggestion may be a supplement of Huygens-Fresnel principle.Based on this new suggestion,a series of new beam was invented,both outside and inside laser cavity.Especially,a new CO2 laser with equivalent beam quality factor Me<1 is achieved.It can be considered as the result of some controllable nonlinear self-focusing.

关 键 词：光束质量 非线性自聚焦 激光
