超高光束质量研究
-
摘要: 提出了边界波具有p 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。Abstract: A new suggestion that there is a phase jump of p 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 Me2 <1 is achieved. It can be considered as the result of some controllable nonlinear self –focusing.
