Abstract

The numerical simulations of possibility of effective delivery of the speckled laser beam energy through the optical heterogeneous medium onto a target have been carried out. The calculations of speckled beam have been carried out within the framework of a numerical model of integration of the parabolic equation for the laser field amplitude taking into account the turbulence according to the phase screens model. Two approaches for pointing the speckled laser radiation onto the target in far field have been considered: the first approach is concerned with the preliminary scanning of the focal plane by the beam with the subsequent SPG correction of the beam position, and the second approach is the direct tip-tilts SPG correction without scanning. The probability estimation of the performance efficiency of the pointing system has been performed. It is shown that in both cases it is possible to direct the most intensive speckle of the laser beam onto the target with high probability.
