Abstract
In this paper, we investigate the creation of a new type of laser beams family by illuminating a curved fork-shaped hologram, with an input Bessel Gaussian beam modulated by a Bessel grating. The theoretical and the numerical results showed that, at the output plane, a high order spiraling Bessel beam is produced. The analytical expressions of the diffracted wave field amplitude and intensities are calculated and analyzed using the stationary phase method. The numerical simulations are given to illustrate our analytical results for different parameters. (C) 2017 Elsevier GmbH. All rights reserved.
