This paper describes the propagation of gaussian beams in the absence of turbulence. It is meant as a reference document.
Introduction
In this appendix, we review the approach of Andrews1 for describing the Gaussian beam propagation using nondimensional parameters. First we introduce the approach for ideal Gaussan Beams and then extend it for non-ideal beams that have M2>1.
