论文摘要
我们报告了单一原子的动力全息镊子的实验实现。镊子通过在液晶空间光调节器上显示的动态相全息图实现。我们在实验上证明了具有这种动态电位并研究其局限性的可能性。我们的结果表明,镊子中单个原子的高概率转移可能会以大步骤进行,比陷阱腰大得多。我们讨论了全息陷阱中的强度闪光,以抑制其抑制作用。测量动态镊子中的损耗和加热率,与静态陷阱相比,未观察到多余的损失或加热。
We report an experimental implementation of dynamical holographic tweezers for single trapped atoms. The tweezers are realized with dynamical phase holograms displayed on the liquid crystal spatial light modulator. We experimentally demonstrate the possibility to trap and move single rubidium atoms with such dynamic potentials, and study its limitations. Our results suggest that high probability transfer of single atoms in the tweezers may be performed in large steps, much larger then the trap waist. We discuss intensity-flicker in holographic traps and techniques for its suppression. Loss and heating rates in dynamic tweezers are measured and no excess loss or heating is observed in comparison with static traps.
