Abstract

Theoretical investigation self-action effects of Quadruple-Gaussian (Q.G) laser beams in media possessing cubic–quintic nonlinearity in their dielectric properties has been presented. Numerical solution of the nonlinear Schrodinger wave equation for the field of incident laser beam has been obtained by making the use of moment theory approach. Particular emphasis is laid on the dynamical variations of the spot size and longitudinal phase of the laser beam with distance of propagation. Self-trapping of the laser beam resulting from the balance between diffraction broadening and nonlinear refraction has been also investigated.
