Abstract

A method is described for modeling a Gaussian beam that travels along an axial or oblique path of a principal ray in a meridional plane. The method uses paraprincipal rays, which are traced adjacent to the ray by using a YNU ray trace procedure that is based on Coddington’s equations. Formulas are principal given that relate the parameters of the Gaussian beam to the heights and slopes of the paraprincipal rays. Two ray trace examples are provided.
