| Abstract: | This paper studies the propagation properties of Hermitian-Gaussian(H-G) beams passing through the hard-edged diaphragm with Gaussian distribution.The approximate analytical propagation equation is derived by means of expansion of the hard-edged diaphragm function into a finite sum of complex Gaussian functions.Numerical calculation examples are given for the intensity of Hermitian-Gaussian beams through a thin lens. |
