Abstract :
Formation of the given laser beam intensity and phase is important to solve practical and scientific problems. Bimorph flexible mirror is one of the most widely used devices for this purpose. In the work we present results of numerical and experimental formation of the vortex beam by means of the bimorph flexible mirror. To determine the required electrode grid we have developed a unique algorithm that allows finding the best suited semipassive bimorph mirror electrode spacing for reproducing almost all arbitrary specified phase profiles
