Optimization of laser propagation for extensive turbulent atmospheric paths in conditions of thermal blooming

Test data of a propagation of the CW laser radiation for extensive weak sloping atmospheric paths are studied in this paper. The calculations are carried out in the limits of the small-angle equation for a coherence function of the second order describing the partially coherent beam self-action. The gas absorption was taken into account in frameworks of the average seasonal summer model of an atmosphere. The average cyclic and the colvanic models of an atmosphere were used for aerosol attenuation. High-altitude vertical profiles of turbulent fluctuations of a refractive index were determined for best, average and worst turbulent conditions. Calculations were obtained for radiation sources located at altitudes from 10 Km up to 25 Km. Paths up to 500 Km were considered. Let's note, that it is necessary to take into account an influence of the Earth surface curvature for these paths. The initial power, the initial beam focusing and the wavelength of radiation were optimized.
