摘要 原子与驻波场相互作用时吸收一个光子并受激辐射一个光子,从而得到2hk的动量。这样,原子将偏转一个角度φ=λ_(dB)/d_(light)。这一过程只改变原子的动量而不改变其能量。可见可以通过光驻波场来改变原子的运动,实现原子的折射、衍射、聚焦等。原子被驻波的折射早已被观察,如Na原子束被共振驻波的折射及被不均匀的激光场的选择性反射。最近还观察到He原子被一个大周期的驻波场的聚焦。 Atomic matter-wave interferometry has attracted our much attention becauseof its interesting prospects in fundamental research and practical applications. Anew tend has appeared on the study of matter-wave interferometry in recentyears. In this paper we describe the principal, applications and review the recentresearch progress.
