Abstract

The results are presented of experimental studies of a possibility of compensating for aberrations of the initial wavefront of an optical beam by the aperture sensing technique based on the atmospheric backscatter signal of radiation from an additional laser source at a different wavelength. The technique allows reducing the beam wavefront aberrations by several times, down to 1–2 wavelengths, at optimal angles of view of the scattered radiation receiver. As a result, the distortions of the intensity distribution in a beam cross section and beam divergence decrease and the power in the beam paraxial region increases.
