title: Diffraction-limited laser beam shaping by use of computer-generated holograms with dislocations.
abstract: A new method that reshapes a Gaussian laser beam into a polygon of diffraction-limited size with a flat or a pyramidal top is presented. The technique is based on the use of computer-generated holograms with phase dislocations (singularities).
