论文摘要
我们使用飞秒激光加工报告了碱金属蒸气细胞的制造。这项激光写入的蒸气电池（LWVC）技术允许任意形状的3D内部体积，并具有与光子结构和光学组件集成的潜力。我们使用不可蒸发的刺痛器来分配Rubidium和吸收缓冲气体。这使我们能够生产具有无真空设备的亚气流缓冲气体压力的细胞。我们证明了用单个LWVC的单次吸收光谱和单光光学磁力测定法。 LWVC技术可能会在微型原子量子传感器和频率参考中找到应用。
We report the fabrication of alkali-metal vapor cells using femtosecond laser machining. This laser-written vapor-cell (LWVC) technology allows arbitrarily-shaped 3D interior volumes and has potential for integration with photonic structures and optical components. We use non-evaporable getters both to dispense rubidium and to absorb buffer gas. This enables us to produce cells with sub-atmospheric buffer gas pressures without vacuum apparatus. We demonstrate sub-Doppler saturated absorption spectroscopy and single beam optical magnetometry with a single LWVC. The LWVC technology may find application in miniaturized atomic quantum sensors and frequency references.
