  • Online:2008-03-25 Published:2008-03-20

Abstract: From the gradient force upon an electric dipole in non-uniform electromagnetic field, the magnitude of the optical gradient force on a dielectric microsphere in light field is proportional to the field gradience and the principle of a single beam gradient laser trapping a dielectric microsphere are derived.

Key words: electric dipole, gradient force, optical trapping
