Genetic Algorithm for Intracavity Bimorph Mirror Control
We implement a new 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 far-field. 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 Bessel Gauss beam shape in near field and experimental extracavity M2-factor reduction almost in 4 times
