Abstract
The propagation characteristics of Hermite_cosine_Gaussian beams passing through an ABCD optical system with hard_edge aperture were studied,By means of expansion of the window's function of the hard_edge aperture into a finite sum of complex Gaussian functions,the approximate analytical propagation equations of laser beams were derived.This method is superd in its reduction of computing time,together with the convenience furnished in analyzing physically the propagation properties of laser beams.
