Abstract

Recently developed version of the modified generalized method of moments for misaligned astigmatic beams in nonlinear waveguides is compared with the direct numerical scheme making use of Gauss-Laguerre decomposition of the asymmetric beam profile. It is demonstrated that the approximation of the beam by a flexible generalized Gaussian function provides a correct description of the global beam behavior even for relatively strong nonlinearities.
