论文摘要
我们展示了一个微型且高度健壮的系统，用于在热原子蒸气上对基于冷原子的量子技术所需的三个频率进行无多普勒光谱。添加剂制造技术的应用以及有效使用光学组件，产生一个紧凑，稳定的光学系统，体积为0.089 L，重量为120 g。该设备的占数量的十分之一，其成本比传统的光谱系统低得多，但也为环境干扰提供了出色的稳定性。我们表征了系统对环境温度在10到30 $^{\ circ} $ c之间的变化的响应，并暴露于0-2000 Hz之间的振动，发现该系统尽管发生了很大的振动噪声和温度变化，该系统仍可以可靠地执行光谱测量。我们的结果表明，3D打印的光学系统是便携式量子技术的绝佳解决方案。
We demonstrate a miniaturised and highly robust system for performing Doppler-free spectroscopy on thermal atomic vapour for three frequencies as required for cold atom-based quantum technologies. The application of additive manufacturing techniques, together with efficient use of optical components, produce a compact, stable optical system, with a volume of 0.089 L and a weight of 120 g. The device occupies less than a tenth of the volume of, and is considerably lower cost than, conventional spectroscopic systems, but also offers excellent stability against environmental disturbances. We characterise the response of the system to changes in environmental temperature between 10 and 30$^{\circ}$C and exposure to vibrations between 0 - 2000 Hz, finding that the system can reliably perform spectroscopic measurements despite substantial vibrational noise and temperature changes. Our results show that 3D-printed optical systems are an excellent solution for portable quantum technologies.
