Abstract

New classes of analytical solutions to a problem of nonlinear interaction of laser waveguide modes without axial symmetry have been obtained. These solutions predict the possibilities of controlled nonlinear focusing of elliptical energy distributions into a point or a narrow extended area. Another possibility leads to an elliptical distribution defocusing. These distribution-controlled evolutions may have a steady or oscillating character related to the competition between the nonlinear and diffraction effects.
