Generation of generalized spiraling Bessel beams of arbitrary order by curved fork-shaped holograms

Abstract

Generalized spiraling Bessel beams (GSBB) of arbitrary order are created by illuminating a curved fork-shaped hologram (CFH) by Laguerre–Gaussian beam (LGB). The analytical expressions of the diffracted wave field amplitudes and intensities are calculated and analyzed using the stationary phase method. The numerical results are given to understand the features of the GSBB by using CFH. Our finding provides the study of the LGB with null mode number n and azimuthal mode index l and the fundamental Gaussian beam through the considered optical system, which are as particular cases of the present investigation.
