论文摘要
我们提出了一种新型的紧凑型和全玻璃基蒸气细胞，整合了空心的光子晶体纤维。没有金属，就像在传统的真空室和更紧凑的几何形状中一样可以进行快速和均匀的加热。结果，我们可以在几分钟到几个小时的时间内填充纤维的时间更快。此外，全玻璃设计可确保沿纤维沿着光学访问。这允许通过测量来自原子的频率依赖性荧光来实时监测rubidium原子在空心核心内的扩散。使用5级bloch方程系统在数值上检索原子密度。
We present a new type of compact and all-glass based vapour cell integrating hollow-core photonic crystal fibres. The absence of metals, as in a traditional vacuum chamber and the much more compact geometry allows for fast and homogeneous heating. As a consequence we can fill the fibres on much faster timescales, ranging from minutes to hours. Additionally the all-glass design ensures optical access along the fibre. This allows live monitoring of the diffusion of rubidium atoms inside the hollow-core by measuring the frequency-dependent fluorescence from the atoms. The atomic density is numerically retrieved using a 5-level system of Bloch-equations.
