在最后稳定共振处操作近同心腔

Operating a near-concentric cavity at the last stable resonance

Chi Huan Nguyen, Adrian Nugraha Utama, Nick Lewty, Christian Kurtsiefer

摘要:

球面镜的近同心光学腔可以在需要强原子-光相互作用的应用中提供优于常规近平面腔的技术优势,因为它们将光集中在非常小的空间区域中。然而,这种腔几乎不支持稳定的光学模式,因此带来了实际挑战。在这里,我们提出了一个实验,在该实验中,我们将近同心腔保持在其最后谐振长度,用于与原子跃迁谐振的780 nm激光。此时,两个球面镜表面的间距比临界同心点短207(13)nm,对应于稳定性参数g=-0.999962(2)和2.4 $μ$ m的腔束腰。

英文摘要:

Near-concentric optical cavities of spherical mirrors can provide technical advantages over the conventional near-planar cavities in applications requiring strong atom-light interaction, as they concentrate light in a very small region of space. However, such cavities barely support stable optical modes, and thus impose practical challenges. Here, we present an experiment where we maintain a near-concentric cavity at its last resonant length for laser light at 780 nm resonant with an atomic transition. At this point, the spacing of two spherical mirror surfaces is 207(13) nm shorter than the critical concentric point, corresponding to a stability parameter g=-0.999962(2) and a cavity beam waist of 2.4 $μ$m.
