摘要: 对焦移的处理有两种不同方法,即Li-Wolf法和Greene-Hall法。以复宗量拉盖尔高斯光束为典型例,对处理焦移的这两种方法作了详细的比较研究,并对数值计算结果作了分析。所得结论对某些实际应用是有意义的。

Abstract: There are two different approaches to deal with focal shifts,i.e.,Li-Wolf's and Greene Hall's approaches.In this paper focal shifts in elegant(complex-argument)Laguerre-Gaussian(ELG)beams are taken as a typical example,a detailed comparative study of the two approaches is made and numerical calculations results are illustr ated.The conclusion made in this paper is useful for some practical applications.
