摘要:

我们报告的实验实现的原子光学装置,允许扫描的原子束。我们在玻璃表面上利用时间调制的倏逝波场来激发亚稳态氖原子的掠入射连续光束。衍射角和效率分别由调制频率和调制形式控制。通过数值模拟获得的优化形状,我们能够将超过50%的原子转移到一阶光束中,我们能够在8 mrad的范围内移动。

英文摘要:

We report on the experimental realization of an atom optical device, that allows scanning of an atomic beam. We used a time-modulated evanescent wave field above a glass surface to diffract a continuous beam of metastable Neon atoms at grazing incidence. The diffraction angles and efficiencies were controlled by the frequency and form of modulation, respectively. With an optimized shape, obtained from a numerical simulation, we were able to transfer more than 50% of the atoms into the first order beam, which we were able to move over a range of 8 mrad.
