我们观察到两个交叉的强光学驻波在受控时间相位差下对准直热铷光束的弹性散射。原子的偏转通过荧光检测在二维空间上解析。时间相位差被认为是原子运动学的重要参数。我们的实验观察结果与蒙特卡罗模拟非常吻合。
We have observed elastic scattering of collimated thermal rubidium beam by two crossed intense optical standing waves with controlled time-phase difference. The deflection of the atoms is spatially resolved in two dimensions by means of fluorescence detection. The time-phase difference is identified as an important parameter for the kinematics of the atoms. Our experimental observations are in good agreement with a Monte Carlo simulation.
