我们最近报道了一项原理验证实验，证明了在静态电位叠加的单束偶极子阱中离子的光学捕获[Nat. Photonics, 4,772—775(2010)]。在这里，我们首先讨论了实验程序，重点是静电势的影响和后果。如果不仔细选择它们的结构，这些势可以很容易地阻止成功的光捕获。然后，我们分析了不同分析模型下的偶极阱实验，其中采用了不同的近似。根据这些模型，实验结果符合反冲加热作为相关加热效应的理论。此外，还开发了蒙特卡罗模拟来完善分析。它揭示了静电势对偶极子阱实验的一般影响。虽然它支持实验中使用的参数的分析模型的结果，但分析模型对显著不同的参数不再有效。最后，我们提出了未来实现光捕获离子实验的技术改进。
We recently reported on a proof-of-principle experiment demonstrating optical trapping of an ion in a single-beam dipole trap superimposed by a static electric potential [Nat. Photonics 4, 772--775 (2010)]. Here, we first discuss the experimental procedures focussing on the influence and consequences of the static electric potential. These potentials can easily prevent successful optical trapping, if their configuration is not chosen carefully. Afterwards, we analyse the dipole trap experiments with different analytic models, in which different approximations are applied. According to these models the experimental results agree with recoil heating as the relevant heating effect. In addition, a Monte-Carlo simulation has been developed to refine the analysis. It reveals a large impact of the static electric potential on the dipole trap experiments in general. While it supports the results of the analytic models for the parameters used in the experiments, the analytic models cease their validity for significantly different parameters. Finally, we propose technical improvements for future realizations of experiments with optically trapped ions.
