论文摘要
我们提出并展示了一种新方法，用于多普勒冷却捕获的离子晶体，其中微动振幅的分布可能很大且不均匀。该技术使用与陷阱RF同步的多普勒冷却光的脉冲，当它们的速度靠近节点时，它们有选择地靶向离子，从而通过单个冷却光的音调在晶体上更加均匀地冷却。我们布置了一个理论框架，描述了该技术是实用的位置，并提供了简单的实验演示。
We propose and demonstrate a new method for Doppler cooling trapped-ion crystals where the distribution of micromotion amplitudes may be large and uneven. The technique uses pulses of Doppler cooling light synchronized with the trap RF that selectively target ions when their velocity is near a node, leading to more uniform cooling across a crystal by a single tone of cooling light. We lay out a theoretical framework that describes where this technique is practical, and provide a simple experimental demonstration.
