We present a novel cold strontium atom source designed for quantum sensors. We optimized the deceleration process to capture a large velocity class of atoms emitted from an oven and achieved a compact and low-power setup capable of generating a high atomic flux. Our approach involves velocity-dependent transverse capture of atoms using a two-dimensional magneto-optical trap. To enhance the atomic flux, we employ tailored magnetic fields that minimize radial beam expansion and incorporate a cascaded Zeeman-slowing configuration utilizing two optical frequencies. The performance is comparable to that of conventional Zeeman slower sources, and the scheme is applicable to other atomic species. Our results represent a significant advancement towards the deployment of portable and, possibly, space-based cold atom sensors.

高通量锶原子源

我们提出了一种专为量子传感器设计的新型冷锶原子源。我们优化了减速过程，以捕获从烤箱中发射的大速度级原子，并实现了能够产生高原子通量的紧凑且低功耗的装置。我们的方法涉及使用二维磁光陷阱对原子进行速度相关的横向捕获。为了增强原子通量，我们采用定制磁场，最大限度地减少径向光束扩展，并结合利用两个光学频率的级联塞曼减速配置。其性能与传统的塞曼慢速源相当，并且该方案适用于其他原子种类。我们的结果代表了便携式和可能的天基冷原子传感器部署的重大进步。
