Abstract We propose a novel scheme to guide cold atoms using a blue-detuned TE01 doughnut mode in a hollow metallic waveguide, calculate the electromagnetic field distribution of the TE01 mode in the hollow metallic waveguide, and compare the attenuation characters of the EH11 and TE01 mode in the hollow metallic waveguide. We also calculate the optical potential of the TE01 doughnut mode for two-level 85Rb atoms and estimate the photon scattering rate. It is found that when the detuning δ= 300GHz, the photon scattering induced heating can be neglected, and the optical potential (Umax about 570mK) of the TE01 mode is high enough to load cold atoms (120μK) from a standard magneto-optical trap and to guide them in the hollow metallic waveguide, which is a desirable scheme to realize a computer-controlled atom lithography with an arbitrary pattern.
