Atomic vapour cells are an indispensable tool for quantum technologies (QT), but potential improvements are limited by the capacities of conventional manufacturing techniques. Using an additive manufacturing (AM) technique—vat polymerisation by digital light processing—we demonstrate, for the first time, a 3D-printed glass vapour cell. The exploitation of AM capacities allows intricate internal architectures, overprinting of 2D optoelectronical materials to create integrated sensors and surface functionalisation, while also showing the ability to tailor the optical properties of the AM glass by in-situ growth of gold nanoparticles. The produced cells achieve ultra-high vacuum of 2 × 10⁻⁹ mbar and enable Doppler-free spectroscopy; we demonstrate laser frequency stabilisation as a QT application. These results highlight the transformative role that AM can play for QT in enabling compact, optimised and integrated multi-material components and devices.

用于下一代量子技术的功能化原子蒸气池的增材制造


原子蒸气池是量子技术 （QT） 不可或缺的工具，但潜在的改进受到传统制造技术能力的限制。使用增材制造 （AM） 技术（通过数字光处理进行还原聚合），我们首次展示了 3D 打印的玻璃均温池。AM能力的利用允许复杂的内部架构，2D光电材料的叠印以创建集成传感器和表面功能化，同时还显示了通过金纳米颗粒的原位生长来定制AM玻璃光学特性的能力。产生的样品池可实现 2 × ^10-9 mbar 的超高真空，并支持无多普勒光谱;我们将激光稳频作为 QT 应用进行演示。这些结果凸显了增材制造在实现紧凑、优化和集成的多材料组件和设备方面可以为 QT 发挥的变革性作用。
