傍轴光束传输的统计行为
Statistical Propagation Behaviors of Paraxial Beams
摘要
对一个任意的傍轴光束,只要给定了任一起始截面上的光场分布情况,则其在自由空间中传输的统计行为就可完全确定了,而且可用“等效高斯光束”来进行描述。给出了相应的传输参数,它们完全确定于起始截面的光场分布情况。利用“嵌入高斯光束”的概念将文献[5]中的结果推广到更为普遍的情形。
Abstract
In this paper, the statistical behabiors are analysed for an arbitrary paraxial beam with two dimentional distribution in the transverse section, and the propagation parameters are obtained for the equivalent Gaussian beam which can describe the statistical behaviors of the paraxial beam. The results in reference can be derived from the conclusions in this paper by using the concept of “embedded Gaussian beam”. This results can be used in the geometrical description for the propagation of a paraxial beam.
