摘要：
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 P-gen/P-noise similar to 4 up to P-gen/(noise) = 10(6)-10(7).
