Abstract
AbstractThe Possibility of the application of the finite element method to some problems of nonlinear optics is investigated in this paper. The self‐action of a light beam in a nonlinear medium is considered. The general approach to the cretion of conservative computation schemes is presented, based on varitional principles. Definite schemes, which are applicable for the problem of thermal self‐action, are described in detail both in the case of cylindrical and or rectangular co‐ordinates. The accuracy and convergence of the models are analysed. The results of computation of the self‐action problems in motionless and moving media are presented.
