Abstract
The present paper is devoted to the application of the phase conjugation method for the thermal blooming compensation. Analysis of the numerical experiment data has shown that the appearance of continuous auto-oscillations in adaptive system is connected with the occurrence of dislocations in the reference beam. The use of the Hartmann sensor with low spatial resolution and modal estimation of the phase results in smoothing the phase estimate and damps the AOS oscillations.
