摘要

提出了一种高精度、高采样率的原子干涉仪，该干涉仪采用两个反向传播的87Rb原子连续冷原子束作为陀螺仪。由二维+磁光阱(MOTs)直接产生两个原子束源，其通量约为3×109原子/s，平均纵向速度为10 m/s。实验证明了中心条纹宽度为54 Hz的拉曼-拉姆齐干涉。

An Atom SAGNAC Interferometer With Continuous Cold Atomic Beam Sources

We present an atom interferometer with two counter-propagating continuous cold atomic beam of 87Rb atoms as a gyroscope with high accuracy and high sampling rates. Two atomic beam sources are generated directly from 2D+ Magneto-Optical Trappings (MOTs) with the flux of about 3×109 atoms/s and mean longitudinal velocity of 10 m/s. Raman-Ramsey interference is experimentally demonstrated with the central fringe width of 54 Hz.
