摘要
The circular Airy vortex beams (CAVB) are attractive owing to their intriguing properties, such as autofocusing, and self-healing. In this paper, we experimentally study optical manipulation and rotation of the silica micro-particles by the use of the autofocusing circular Airy vortex beams, and analyze the dependence of rotational velocity on the topological charges. Experimental results prove that the circular Airy vortex beams have autofocusing property. With the increase of topological charges, the rotational velocity of the micro-particles first increases and then decreases after reaches a maximum. Optical trapping technology based on CAVB may enrich the possibility and manner for optical trapping and guiding micro-particles.
