Paper Abstract

Compensation for light beam distortions in the atmosphere using the phase-conjugate mirror based on stimulated Brillouin scattering is investigated both experimentally and theoretically. Correction of beam distortions caused by turbulent medium, atmospheric aerosol, and thermal self-action is considered. It is shown that as the structural characteristic of fluctuations in turbulent medium permittivity and the length of the medium increase, the correction accuracy parameter decreases. This parameter reduction follows the decrease in typical thermal self- action length of repetitive pulse radiation in the moving atmosphere. The correction accuracy parameter value decreases down to 0.5 only, as the optical depth of aerosol medium increases up to 3.0.
