Title

Optical Transportation of Micro-Particles by Non-Diffracting Weber Beams

Abstract

The optical transportation of solid polystyrene particles by the non-diffracting Weber beams is demonstrated with both forward and backward motion along the parabolic main lobes of Weber beams in three dimensions. The Weber beams are generated from the complex field modulation based on the spatial light modulator for realizing the optical transportation of micrometer polystyrene particles in an optical tweezers setup. The particle motion and velocity distribution along the main lobes of Weber beams in two different parabolic shapes are characterized and compared.
