我们提出了一个紧凑的{sup 87}Rb原子源用于高精度双原子干涉仪。该源基于双级磁光阱（MOT）设计，由二维（2D）磁光阱组成，可有效加载3d磁光阱。积聚的原子被精确地发射到水平移动的糖蜜中。我们的源产生高原子通量（bbb10 {sup 10}原子/s），具有高分辨率Sagnac原子干涉测量所需的精确和灵活可调的原子轨迹。我们利用飞行时间技术和速度选择性拉曼跃迁，根据发射原子的相关参数，即温度、绝对速度和指向来表征源的性能。
We present a compact {sup 87}Rb atomic source for high precision dual atom interferometers. The source is based on a double-stage magneto-optical trap (MOT) design, consisting of a two-dimensional (2D) -MOT for efficient loading of a 3D-MOT. The accumulated atoms are precisely launched in a horizontal moving molasses. Our source generates a high atomic flux (>10{sup 10} atoms/s) with precise and flexibly tunable atomic trajectories as required for high resolution Sagnac atom interferometry. We characterize the performance of the source with respect to the relevant parameters of the launched atoms, i.e., temperature, absolute velocity, and pointing, by utilizing time-of-flight techniques and velocity selective Raman transitions.
