Abstract: The high-intensity singular beam turns out to be created by means of the ordinary cover glass for a microscope. For this it is necessary to place the edge of the cover glass into the high-power fundamental laser beam. At the expense of the technical wedging of the cover glass beyond the transparent appears the high-quality singular beam bearing the optical vortex. The given paper represents the physical mechanism of such process illustrated with the vast experimental and theoretical results.
