Abstract

Numerical calculations of focusing a laser beam on a remote receiver through the turbulent atmosphere using an adaptive optical system have been carried out. The adaptive optical system has been realized the phase conjugation of the outgoing laser beam to a reference one. The adaptive phase correction of both laser and reference beams assume to be imperfect. The research is devoted to obtaining simple estimations of laser intensity at the receiver, which would agree with calculation results. It is proposed to conduct these estimations on the basis of information on the parameters of both laser and reference partially corrected beams. Since there is no way to associate the laser intensity at the receiver with an angular divergence of corrected beams, it has been proposed to estimate the on-axis laser intensity at the remote receiver basing on the correlation characteristics of residual phase of both laser and reference beams.
