Abstract
The results are presented of atmospheric experiments on compensation for the artificially introduced initial aberrations of the wavefront of a focused laser beam using the aperture sounding method based on an atmospheric backscatter signal from an additional source at a different wavelength. It is shown that adaptive compensation can reduce the amount of wavefront distortions, increase the backscatter signal, and restore the focusing of the main laser beam
