Paper Abstract

The transverse beam profile of solid-state lasers is a key issue for determining its propagation properties. Herein, we address laser beam distortions caused by thermal lensing and birefringence. For the simulations a finite difference method is used for the description of beam propagation problems. The method is an improved approach to the solution of the wave equation in paraxial approximation. Provided that steady-state conditions prevail, in comparison with the Fresnel-Kirchhoff integral description this method allows for a fully 3 D treatment of the aforementioned laser-optical phenomena.
