Abstract:

Efficiency of phase-conjugated correction of random wavefront tilts is studied to shape laser beams propagating through the turbulent atmosphere. Amplification of the average intensity of radiation and degree of suppression of the intensity fluctuations on the beam axis in the receiving plane chosen as perfomance figures of the correction efficiency are analyzed. Assuming that the correction for random tilts is practically identical to control of the random shifts of the beam's energy center of gravity we have avaluated the relative contribution of the latter to the diminishment of the average intensity of collimated beams with the Fresnel number of the order of unity.
