单色光束的衍射度

Degree of diffraction for monochromatic light beams

Jie Wu, Shuang-Yan Yang, Chun-Fang Li

摘要:

定义了一个称为衍射度的参数来描述单色光光束的衍射扩展。与Gawhary和Severini在Opt.Lett中引入的傍轴度相同。33,1360(2008),衍射的程度仅取决于光束的角谱。利用该定义,可以定量地比较不同光束的衍射扩展。

英文摘要:

A parameter, called the degree of diffraction, is defined to describe the diffractive spreading of a monochromatic light beam. The same as the degree of paraxiality that was introduced by Gawhary and Severini in Opt. Lett. 33, 1360 (2008), the degree of diffraction depends only on beam's angular spectrum. With this definition, it is possible to quantitatively compare the diffractive spreading of different light beams.
