A Theoretical Study of Optical Levitation of a Microsphere

Abstract

We theoretically investigated the optical forces exerted on a sphere in order to corroborate the threedimensional optical trapping of a micro object by the laser heaths from plural optical fiber ends. which were inserted at an angle to a sample chamber. From these investigations, we verified that there was only one stable point of equilibrium located below the bean-crossing point and greatly enhanced stability could be obtained.
