Generation of vortex by light-induced phase mask in a V-type atomic system

Optical vortices on a weak probe beam were generated by a strong pump beam with a vortex array or an L-shape stripe. We also observed a pair of vortices having opposite charges with the total charges conserved.

Laser beams with embedded vortices: tools for atom optics

Narupon Chattrapiban, Elizabeth A. Rogers, Ilya Arakelyan +2 more

Two-dimensional spatial light modulators have been employed to create static and dynamic phase masks for embedding multiple vortices and exotic intensity-void structures in laser beams. A variety of patterns of singularities, producing dark longitudinal and transverse intensity channels, have been created. The uniformity, quality, and suitability of these patterns as elements for atom optics (e.g., atom-tunnel beam splitters) have been studied as a function of the phase quantization level and spatial resolution of the phase mask. Specifically, we show that (1) high-quality modes, those that propagate long distances and can be focused, can be generated when the number of phase steps between 0 and 2pi on the phase mask exceed four and (2) atom confinement increases with the charge of the vortex.

Multiplexed vortex beam-based optical tweezers

Francisco Misael Muñoz Pérez, Ferrando, Vicente, Walter D. Furlan +3 more

The design and implementation of a multiplexed spiral phase mask in an experimental optical tweezer setup are presented. This diffractive optical element allows the generation of multiple concentric vortex beams with independent topological charges. The generalization of the phase mask for multiple concentric vortices is also shown. The design for a phase mask of two multiplexed vortices with different topological charges is developed. We experimentally show the transfer of angular momentum to the optically trapped microparticles by enabling orbiting dynamics around the optical axis independently within each vortex. The angular velocity of the confined particles versus the optical power in the focal region is also discussed for different combinations of topological charges.
