驻波场中相位迟后的偶极力

计算了二能级原子在一个驻波场中的辐射压力，给出了在不对空间平均时的辐射压力的普遍表达式，指出辐射压力的零级项应应于受激压力，而一级项对应于偶极力，高队项则可忽略。文中详细地计算了各种不同情况下的偶极力和相位，指出对于不同速度，相位有不同的迟后，这样的结果将严重地影响原子在驻波场中的动力学，用光子再分配模型简单地对有力的相位随速度的变化作了解释。

Dipole Force with Retarded Phase in a Standing Wave

The radiation force on a two-level atom in a sounding wave is calculated in thispaper,and the general expression of radiation force without spatial average is given.It isshown that the zero-order force corresponds to the stimulated radiation force, first-orderto the dipole force, while higher-order can be neglected. The magnitude and phase of thedipole force are given and the dependence of phase on atomic velocity is discussed, whichaffect the dynamics of stoms in a soanding wave. The explanation of phase dependence onatomic velocity is given by the photon redistribution model.
