The results of experiments on the phase correction of a laser beam propagating in a turbulent atmosphere are presented. A scheme was used in which the laser beam of the main radiation, formed using an adaptive optics system, propagated along a horizontal atmospheric path. To ensure the operation of the AO system, a signal was used from a reference source generated by cw-laser radiation at a wavelength of 0.532 μm, which propagated towards the main one. At the transmitter, the optical beam from the main laser is formed using the adaptive optics system and directed into the atmosphere by the Newton telescope. The main radiation laser is focused through the atmospheric layer into the receiving plane. A reflecting screen, a photodetector based on the small astronomical telescope Celestron, and a reference laser, which propagated towards the main one, were located in this plane.
