Abstract

We highlight the properties and the physics of a special kind of structured light, namely when two counter-propagating Laguerre-Gaussian optical beams interfere with their focal planes shifted axially by a finite distance d. We distinguish between two different situations: the back-to-back (d<0) and face-to-face (d>0) cases and show how these lead to finite ring lattices, Ferris-wheels and conveyor belts between the focal planes. Furthermore, even in the case of shifted Gaussian beams a new all-optical atom trapping environment is shown to arise due solely to the scattering force on atoms at near resonance when the beam waists are of sub-wavelength dimensions. Our findings are discussed with reference to sodium atoms.
