The efficiency of multi-channel laser radiation focusing through the optically inhomogeneous medium under its phasing on the system output and in the target-in-the-loop technique

Numerical investigations of the multi-channel laser radiation focusing through the optically inhomogeneous medium at the phasing on the system output and in the case of target-in-the-loop technique on basis stochastic parallel gradient (SPG) algorithm have been performed. The efficiency of focusing has been investigated depending on the ratio of Fried parameter to the subaperture size.
