Optical dipole potential in an inhomogeneous light field is an important method of realizing the laser cooling and trapping of single atoms. The optical dipole trap in the highfinesse microcavity is discussed, and different confi gur ations of optical potential composed of standing wave and vertical confined beam s are analyzed. It is shown that the submicron scale optical trap could be ob t ained in this microcavity with the potential depth of about mK. The strong cou pling of atom and the cavity mode can be realized. We also discuss the effect of laser line width on the depth of potential well.
