Paper Abstract

The work deals with phenomena affecting propagation and amplification of radiation in a high power laser system. The studies were performed by means of numerical modeling. The parabolic equation is used to describe the laser beam propagation. The equation includes diffraction, amplification with saturation, self-focusing and thermo-optical effects. The code also includes apodization, relaying, and spatial filtration. Cylindrical symmetry is assumed. The influence of aberration of a soft dielectric diaphragm on intensity distribution is described. Some phenomena caused by self-focusing are investigated. It is shown that, first of all, the self-focusing but not amplification saturation limits pulse energy which may be delivered from the laser under consideration.
