Abstract

Two independent methods for Gaussian spot size measurement are experimentally compared. The two methods use a Ronchi ruling where the transmitted total power and the normally diffracted energy are considered. We show that the beam widths obtained by these methods are very close. The theory of diffraction used is based on the Rayleigh-Sommerfeld integral equation with Dirichlet condition.
