Abstract

It is developed the theory of diffraction of a singular light beam with axial optical vortex on a half-plane screen, which cuts off the vortex zero-amplitude center ('severe screening'). It is shown that such diffraction features differ strongly from well known diffraction of a light beam with smooth wave front. It was founded that the beam singular properties are restored on some distance behind the screen. It is happened through the complicated space dynamics due to generation of secondary vortices. The main features of severe screened singular beam 'self-treatment' are established.
