| 摘 要： | 通过分析原子的运动对稳态布居的影响,发现双光子共振时的多普勒频移发生在零双光子失谐附近;单光子共振时的多普勒频移发生在零单光子失谐附近;当原子被两束频率相同、传输方向相反的激光驱动时,在零双光子失谐附近双光子共振不产生多普勒频移。

| Abstract: | By analyzing the influence of the motion of the atoms on the steady - state populations of the atomic levels, we found that the Doppler frequency shift in the double - photon resonance occurs near to the zero double - photon detuning and the Doppler frequency shift in the single - photon resonauce near to the zero single - photon detuning. The double - photon resonance near to zero double - photon detuning does not make the Doppler frequency shift occured when atoms are driven by two counter propagating but same frequency laser beams. |
