Double Slit Diffraction of Vortex Photon Beam

Caption

UV radiation from a relativistic electron beam is diffracted by a double-slit. In contrast to the normal light (left), the diffraction shows a deformation in the central part (right), indicating the existence of the phase singularity, which is a definite evidence of the vortex nature.
