Abstract

Using the Galerkin criterion in the basis of flexible generalized Gaussian modes, the equations of motion are derived for the parameters of a misaligned astigmatic twisted Gaussian beam in an axially symmetric nonlinear medium. Nontrivial features of the beam dynamics (e.g., phase locking, cycle generation, nonlinear symmetry change) in a parabolic waveguide with Kerr nonlinearity are revealed.
