Optical vortices generation by digital "blazed" thin holograms
Abstract
Asymmetrization of fringe profile (the so-called "blazing) of thin phase holograms provides the opportunity to increase their diffraction efficiency to nearly 100%. One of popular applications of thin holograms is generation of the optical vortices. The paper considers advantages and special features of using of digital blazing in such fork-like holograms.
