受光阑限制厄米-双曲正弦-高斯光束的解析传输公式
Propagation Expression of Hermite-Sinh-Gaussian Laser Beams Through an Optical System with Hard-edge Aperture
【摘要】 从Collins公式出发,使用厄米多项式展开的方法,对厄米-双曲正弦-高斯光束(HShG)光束通过有硬边光阑限制的近轴ABCD光学系统的传输进行了研究,将其在输出面上的场分布表示成为不完全伽马函数的形式,得出解析表达式。并讨论了该光束的传输特性和该方法的优越性。
【Abstract】 Based on the Collins integral formula,and by the use of the expanding form of the Hermite polynomial,the propagation of Hermite-Sinh-Gaussian(HShG) beams through a paraxial ABCD system with hard-edge aperture is studied.The field distribution on the output is expressed to be that of the incomplete gamma functions and an analytical propagation expression is derived.The propagation properties of the beams and the superiority of this method are also discussed.
