Abstract
We present the results of a numerical study of the possibility of compensating for aero-optical aberration distortions of the beam wavefront by the method of aperture sensing based on the atmospheric backscatter signal. It is shown that the method makes it possible to partially compensate for aero-optical aberrations. The dimensions of a beam in the cross section become several times smaller than of a beam without adaptive control of the wavefront, and the intensity distribution becomes more symmetric about the optical axis.
