摘要：
In this paper the half-plane diffraction of the Gaussian light beam containing an optical vortex is examined. The analysis is performed analytically (scalar theory in the near field approximation). The stability and dynamics of the optical vortex within the diffracted wavefront is investigated. Some examples of diffraction by single slit are also presented. (C) 2000 Elsevier Science B.V.
