标题： Micro-cavity length stabilization for fluorescence enhancement using schemes based on higher order spatial modes

摘要： 我们报道了使用奇数阶高阶空间模式实现高性能腔长稳定性的实验研究。基于高阶模式的方案对于用于增强少数发射体荧光检测的微腔特别有用，这需要最小化从稳定光束泄漏的光子。我们描述了设计和构建一个具有可调高被动稳定性的微腔装置组件。此外，还实施并根据性能表征了不同类型的基于高阶模式的主动稳定技术。我们实现了约0.5 pm RMS的稳定性，同时连续锁模光束泄漏到荧光探测器中的误差光子被抑制了100倍以上。我们预计这些结果对于各种发射体-腔体设置的量子技术实现非常重要，因为这些技术提供了一种有用的工具来满足高度苛刻的需求。 显示英文摘要

摘要： We report on experimental investigation of potential high-performance cavity length stabilization using odd-indexed higher-order spatial modes. Schemes based on higher-order modes are particularly useful for micro-cavities that are used for enhanced fluorescence detection of a few emitters, which need to minimize photons leaking from a stabilization beam. We describe the design and construction of an assembly for a microcavity setup with tunable high passive stability. In addition, different types of active stabilization techniques based on higher-order modes, are then implemented and characterized based on their performance. We achieved a stability of about 0.5 pm RMS, while the error photons leaking from the continuous locking beam to a fluorescence detector are suppressed by more than 100-fold. We expect these results to be important for quantum technology implementations of various emitter-cavity setups, where these techniques provide a useful tool to meet the highly challenging demands.
