摘要：

The propagation characteristics of Hermite-cosine-Gaussian beams passing through an ABCD optical system with hard-edge aperture is 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 are derived. This method is superb in its reduction of computing time, together with the convenience it furnished in analyzing physically the propagation properties of laser beams.
