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.
