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.
