Paper Abstract

In this paper we consider the symmetry of the deposited energy distribution for the case the number of laser beams to be small in the direct compression open GH scheme. We investigate the dependence of asymmetry on the geometry of irradiation, laser intensity profile in a beam and the properties of absorber. Our calculations show that one may obtain the asymmetry at the level not worse than 2-3 percent for Gaussian beams. The magnitude of asymmetry may be written as an integral representation. For 2-beams irradiation it gives conditions for the laser beam profile or absorber.
