摘要：

Optical forces exerted on a microsphere were theoretically investigated in order to corroborate an optical levitation of an object by the laser beams from plural optical fiber ends, which were inserted into a sample cell at an angle. There was only one stable point of equilibrium located below the beam-crossing point and greatly enhanced stability could be obtained. Furthermore, we revealed the feasibility of trapping an object with large relative refractive index. (C) 2001 Elsevier Science B.V. All rights reserved.
