Paper Abstract

Formation of a diffraction limited divergence and obtaining a high contrast of radiation in electric-discharge XeCl laser system due to SBS are investigated. Possibility of a correction of laser beam wave-front distortion on an astigmatic and a spherical aberrations and on a refractive coefficient non-uniformity in optics elements and atmosphere is shown. Correction of laser beam wave-front having the 20- fold distortion of diffraction limited angle using phase- conjugate Brillouin mirror allowed to obtain the initial angle of 2 X 10-5 rad divergence of laser beam. Use the threshold conditions of Brillouin scattering allowed to increase the XeCl laser radiation contrast from Pgen/Pnoise approximately 4 up to Pgen/Pnoise equals 106 - 107.
