WebThe results of an experimental study in optics of waves with screw dislocations are reported. The structure of the screw dislocations of different charges produced by diffraction on the computer-synthesized grating or by nonlinear processes of second- harmonic generation is experimentally studied and discussed.

WebSep 1, 2024 · We study a novel family of mth-order cosine Gaussian optical vortex beams with an infinite (but countable) number of screw dislocations, each with the topological charge m. An expression is derived for the normalized-to-power orbital angular momentum (OAM) of such beams. The OAM is shown to increase quadratically with the order m.
