Abstract
Diffraction of a one-dimensional Gaussian beam by a slit is theoretically investigated. In the visible and microwave regions a new property of the diffracted energy is presented. Analytical expressions for the transmission coefficient and the diffracted energy at normal direction are obtained in simple practical form for experimentalists. These expressions suggest a simple method for measuring Gaussian beams of 1.5-μm diameter or larger.This publication has 12 references indexed in Scilit:
