Abstract : In the present paper, we study the generation of spiraling beams which introduced by the illumination of Flat-topped vortex hollow beam (FtVHB) with curved fork-shaped hologram (CFH). Based on the Fresnel diffraction integral formula, analytical expression for the output amplitudes of the produced beam after diffraction is derived. The variation of the intensity profile of the diffracted beam in longitudinal and radial directions depends on the effect of the incident and the spiraling output fields parameters are given with numerical examples. The present work gives more general characteristic and diffraction by a CFH because the Flattopped and Gaussian beams.
