Theoretical analyses of a doppler-type atomic interferometer

Based on the analyses of a moving three-level atom interacting slantingly with a standing wave laser field, two kinds of atomic interferometries are designed. The coherent splitting, deflection, combination and free propagating of the atomic waves in the two atomic interferometers are studied in detail. The results show that the interference effects resulting from interaction between different internal states of the atom will occur when some conditions are met by both the atom and the light field. Finally, we have analysed theoretically how to realize and demonstrate the atomic interferometry by using the two methods.
