Paper Abstract

In this paper we implement technique of intracavity bimorph flexible mirror control that allows to manipulate laser beam parameters (increase power, decrease divergence) and to form a given intensity profile at any distance including a far-field formation. Intracavity mirror surface profile is controlled by number of voltages calculated by means of genetic algorithm combined with hill-climbing one. Then the traditional Fox-Li approach is applied. It is numerically shown the possibility of successful formation of super Gaussian beam shape in near field, ring-like beam in far-field, possibility of significant power increase of TEM00 mode and far-field peak intensity enlargement.
