Abstract: Transfer of the orbital angular momentum to dielectric microparticles optically trapped using recently discovered asymmetric Laguerre-Gaussian (LG) laser beams is demonstrated. We experimentally show that at a fixed topological charge, increasing beam asymmetry parameter leads to increasing velocity of the polystyrene beads moving along a crescent-shaped path.

Keywords: diffraction theory, optical vortices, propagation, optical trap, orbital angular momentum, Laguerre-Gaussian beam, asymmetry of a laser beam, complex shift.
