Abstract

Based on the hierarchy of mathematical models with regard to parallel algorithms and effective systems, the interaction of a femtosecond-laser pulse with a transparent dielectric medium (fiber-optic glass) is numerically simulated. The features of this interaction are studied for the initial Gaussian and ring distributions of the laser beam. The critical powers at which a local collapse of the beam takes place are determined for the Schrödinger equation. A comparison of the results obtained using various models is presented.
