论文摘要
我们提出了镜头腔过滤器和原子线过滤器之间的比较，讨论了它们在量子光学元件中应用的相对优点。我们描述了透镜腔过滤器的设计，表征和稳定过程，该晶状体滤光管由高反射涂层的市售的Plano-Convex镜头组成，并将其与使用D $ _ {2} $吸收线的超鼻原子带 - 原子量通滤器进行比较。我们发现，可以任意选择腔滤器的峰值传输频率和带宽，但是传输频率受热漂移的影响，并且腔需要稳定以比几个MK更好，而原子过滤器本质上是稳定的，并且与原子共振频率链接在一起，因此可以在非实施环境中使用。
We present a comparison between lens cavity filters and atomic line filters, discussing their relative merits for applications in quantum optics. We describe the design, characterization and stabilization procedure of a lens cavity filter, which consists of a high-reflection coated commercially available plano-convex lens, and compare it to an ultra-narrow atomic band-pass filter utilizing the D$_{2}$ absorption line in atomic rubidium vapor. We find that the cavity filter peak transmission frequency and bandwidth can be chosen arbitrarily but the transmission frequency is subject to thermal drift and the cavity needs stabilization to better than a few mK, while the atomic filter is intrinsically stable and tied to an atomic resonance frequency such that it can be used in a non-laboratory environment.
