【摘要】 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更多还原

【Abstract】 Using the modified effective Hamiltonian for non degenerate Raman process, we calculated the evolution of the atom inversion and studied the influence of AC Stark shift on the collapse revival phenomenon of Rabi oscillations. It is shown that in the presence of AC Stark shift, the atom inversion in non degenerate Raman process has a beatiful periodicity, and the frequency and amplitude of the Rabi oscillation are affected by AC Stark shift.更多还原
