摘要/Abstract

摘要： 本文报道了采用受激拉曼绝热捷径(STIRSAP)方案实现原子干涉仪并提高其鲁棒性的实验研究结果。我们对STIRSAP型拉姆齐原子干涉仪的条纹对比度进行了分析，与传统的受激拉曼绝热通道型拉姆齐原子干涉仪相比，STIRSAP加速了布居数绝热转移过程，提高了原子干涉条纹的对比度。通过调制泵浦光和斯托克斯光的强度，研究了交流斯塔克效应对原子干涉条纹的影响，实验结果表明STIRSAP能有效抑制原子干涉过程中的交流斯坦克效应，提高原子干涉仪的鲁棒性。

Abstract: We report the experimental results of using a new scheme of stimulated Raman shortcut-to-adiabatic passage (STIRSAP) to implement an atom interferometer and improve its robustness. The fringe contrast of the Ramsey atom interferometer using STIRSAP is analyzed. Comparing with the traditional Ramsey interferometer using stimulated Raman adiabatic passage, the adiabatic passage is speeded up in the STIRSAP, and the contrast of the atom interference fringe is improved. By tuning the intensity of the Raman pulse, the phase shift of the atom interference fringe caused by the ac Stark effect is measured. The experimental results show that the STIRSAP effectively suppresses ac Stark effect, and thus improves the robustness of the atom interferometer.
