Abstract
A new method is investigated for synthesis of computer-generated optical elements to focusate the radial-symmetrical laser beam into the complex focal contours--in particular, into the alphabetical-digital symbols. The method is based on decomposition of the focal contour by segments of the straight lines and half-circumferences, following corresponding spacing out of the focusator on elementary segments with a ring shape and solution of the inverse task of focusing from focusator segments into corresponding element of the focal contour. It was determined in the computer experiment that the theoretical efficiency of synthesized focusators into the letters is above 85%.
