Аннотация: The influence of the strong turbulence regime on the laser beam propagation and focusing has been investigated. Turbulence was modeled on the base of the full Navier-Stokes equations which were transformed into the system of the Volterra type. The influence of a source-like term in the energy equation was analyzed. Statistical properties of turbulence were calculated. Computations were compared with experiments. We investigated the propagation of a laser beam with the aid of parabolic equation method. Focusing for linearly and radially polarized beam was considered. The problem of object-targeting system and the propagation of ultra-short laser pulses were also discussed.
