Paper Abstract

In this paper, the expression for the incident strongly focused laser beam is obtained using the complex-source-point spherical wave theory. Based on the scattering theory, the formulas of radiation pressure of Gaussian beam exerted on a homogeneous sphere is obtained. The numerical results of the radiation pressure and their physical interpretations are presented. In our experiment of optical levitation, we find out that particles (one or more) can also be steadily levitated in the beam for a long time without a feedback apparatus.
