Abstract

Adaptive correction for thermal blooming by multidither and phase-conjugation algorithms is analyzed with the use of numerical models of beams propagating in a nonlinear medium. Methods to increase the stability of these algorithms are proposed. The influence of an adaptive mirror on the efficiency and the divergence of correction algorithms is considered. The feasibility of amplitude-phase control with a two-mirror adaptive optics system is also analyzed.
