Description of a multifocal arrangement of asymmetric Kummer-beam optical vortices
Natalia Londoño, Edgar Rueda, Jorge A. Gómez +2
In this work, an analytic expression is derived for the optical field generated by an off-axis Gaussian beam diffracted by a Discrete Vortex-Producing Lens. With this system, a mul…

Analytical description of optical vortex beams generated by discretized vortex producing lenses
Gonzalo Rumi, Daniel Actis, Dafne Amaya +3
Discretized vortex-producing lenses programmed on low performance spatial light modulators have been used for the generation of optical vortices. However, the description of these…
