Abstract
The results of the laboratory experiments on compensation of the laser beam initial wave front aberrations by the stochastic parallel gradient descent algorithm (SPGDA) are presented. It is shown that for wave front aberration, considered in the experiment, optimal choice of the initial and iteration algorithm steps, as well as the optimal coefficient of noise threshold provides for the compensation of the main part of aberrations, using 150–200 iterations of SPGDA.
