| Popis: | In this paper, we investigate the creation of Generalized spiraling Bessel beams by a Fresnel diffraction of a Bessel Gaussian laser beams by curved fork-shaped hologram. The analytical expressions of the amplitude and the intensity distribution of the diffracted wave field are derived using the stationary phase method. The numerical simulations are given to illustrate our analytical results for different parameters. The diffraction of Gaussian beams by curved fork shaped hologram is deduced as particular cases in the present work. |
