Essay

The dissertation is devoted to theoretical and experimental studies of the phase-matching singular beam arrays when the axes of symmetry of the beam belong to the surface of a hyperboloid of revolution. It is shown that the array of singular beams can form an axial high-order optical vortex and also preserve its intensity distribution while propagating and focusing. It is shown a very high orbital angular momentum for the singular beams can be obtained. Experiments and theoretical studies show that diffraction of fundamental Gaussian beam on a stack of dielectric wedges can produce a symmetric array of the phase-matching off-axis beams.
