Paper Abstract

We study theoretically the angular momentum transfer between strongly focused laser vortex beam and a dielectric oblate spheroidal particle (OSP). We find sets of geometrical parameters of the particle and the beam for which the particle is stably trapped on the beam axis in a uniform rotating state, thereby serving as a possible test probe of the global beam angular momentum as well as its spin and orbital parts.
