The effect of the strong turbulence regime on the laser beam propagation and focusing

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.
