Abstract EN
Vortices of different charges are embedded in a wavefront that has quadratic phase variation, and the intensity distribution near the focal plane is studied.
This method may be useful in realizing complicated beam profiles.
We have experimentally demonstrated the generation of vortex arrays having integer as well as fractional topological charges that produce different intensity profiles at the focal plane.
The phase variation realized on a spatial light modulator (SLM) acts as a Fresnel lens with embedded vortices.
