Abstract

Two evanescent fields were generated on prism surface by incidence of two laser beams from opposite side of the prism at total internal reflection angle. Using photon force of these two evanescent fields, a small particle can be moved backward and forward, and trapped on prism surface. The experimental result shows that a latex sphere of radius 10micrometers can be moved automatically between two points with an error of 9 micrometers . Trapping experiment also shows a clear effect on keeping the position of a small particle against the Brownian motion and flow of water.
