Paper Abstract

A preparation method of cold atomic beam with fine optical characteristics is presented and discussed in this paper. The method is described as followings: cold atoms in three-dimension magneto-optical trap (3MOT) are pushed out because of the imbalanceable resonance-radiation pressure and form a cold atomic beam, whose propagation is limited in a magnetic guide. And then the atomic beam is further transversely compressed by use of two-dimension magneto-optical trap (2MOT). Finally, a state preparation laser processes the atomic beam. Consequently, the continuous cold atomic beam with lower longitudinal velocity, higher flux, much less transverse velocity and homogenous state is obtained. The simulation results show that the preparation method is feasible, which can be used in the establishment of the high-property atom interferometer.
