摘要:

本文给出了一个工作在一阶磁不敏感的自由空间原子干涉仪的实验结果|F=1,mF=0> ->| F=2,mF=0>玻色凝聚~(87)Rb原子的跃迁。脉冲原子激光从玻色-爱因斯坦凝聚体输出耦合,并通过一系列两个内部状态分束器传播,通过两个干涉状态之间的相干拉曼跃迁实现。我们观察到拉姆齐条纹的能见度接近100%,并确定当前和潜在的可实现的干涉相位灵敏度。该系统非常适合于测试最近提出的产生和检测压缩原子态的建议。

英文摘要:

We present results on a free-space atom interferometer operating on the first order magnetically insensitive |F=1,mF=0> -> |F=2,mF=0> transition of Bose-condensed 87Rb atoms. A pulsed atom laser is output-coupled from a Bose-Einstein condensate and propagates through a sequence of two internal state beam splitters, realized via coherent Raman transitions between the two interfering states. We observe Ramsey fringes with a visibility close to 100% and determine the current and the potentially achievable interferometric phase sensitivity. This system is well suited to testing recent proposals for generating and detecting squeezed atomic states.
