利用修正后的有效哈密顿量计算非简并拉曼（Ｒａｍａｎ）过程中原子反转的演化，并研究交流斯塔克（Ｓｔａｒｋ）位移对拉比（Ｒａｂｉ）振荡的崩溃和再生的影响。结果发现，交流斯塔克位移的存在使得非简并拉曼过程中原子反转的崩溃与再生现象呈现较好的周期性，并且拉比振荡的频率和振幅均受交流斯塔克位移的影响
The modified effective Hamiltonian is used to calculate the evolution of the atomic inversion in the non-degenerate Raman process and the effect of the exchange Stark displacement on the collapse and regeneration of the Rabi oscillation. The results show that the existence of the exchange Stark shift makes the collapse and regeneration of atomic inversion show a good periodicity in the non-degenerate Raman process, and the frequency and amplitude of the Rabi oscillation are affected by the exchange Stark shift
