我们演示了一个二维（2D）光栅磁光阱（GMOT）与一个单一的输入冷却激光束和平面衍射光栅使用87 Rb。与传统的2D磁光阱（MOT）相比，这种配置增加了实验访问。如本文所述，输出通量为数亿个铷原子/秒，平均速度为16.5（9）m/s，速度分布为4（3）m/s标准差。我们使用来自2D GMOT的原子束来演示具有2.46（7）x 10（8）个原子的三维（3D）GMOT的加载。讨论了提高输出通量的方法。
We demonstrate a two-dimensional (2D) grating magneto-optical trap (GMOT) with a single input cooling laser beam and a planar diffraction grating using 87Rb. This configuration increases experimental access when compared with a traditional 2D magneto-optical trap (MOT). As described in the paper, the output flux is several hundred million rubidium atoms/s at a mean velocity of 16.5(9) m/s and a velocity distribution of 4(3) m/s standard deviation. We use the atomic beam from the 2D GMOT to demonstrate loading of a three-dimensional (3D) GMOT with 2.46(7) x 10(8) atoms. Methods to improve output flux are discussed.
