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.

使用动态全息光镊进行单原子运动

我们报告了用于单个捕获原子的动态全息镊子的实验实现。镊子是通过显示在液晶空间光调制器上的动态相位全息图实现的。我们通过实验证明了捕获和移动具有这种动态势的单个铷原子的可能性，并研究了其局限性。我们的结果表明，镊子中单个原子的高概率转移可能以大步长进行，比陷阱腰大得多。我们讨论了全息陷阱中的强度闪烁及其抑制技术。测量动态镊子中的损耗和加热速率，与静态陷阱相比，没有观察到过多的损耗或加热。
