Laser radiation propagation through the turbulent atmosphere is analyzed in numerical experiments, and efficiencies of phase and amplitude-phase beam control methods are compared. Since complete correction of turbulent distortions is possible only at wave front reversal, realization of this algorithm is considered in an adaptive system having two mirrors separated by a gap, where a beam propagates under free diffraction conditions. This system is shown to be more efficient as compared to the phase conjugation system.
