We demonstrate and characterize a source of Li atoms made from direct metal laser sintered titanium. The source's outgassing rate is measured to be 5(2) × 10 Pa L s at a temperature T = 330 °C, which optimizes the number of atoms loaded into a magneto-optical trap. The source loads ≈10Li atoms in the trap in ≈1 s. The loaded source weighs 700 mg and is suitable for a number of deployable sensors based on cold atoms.
我们展示并表征了一种由直接金属激光烧结钛制成的锂原子源。在温度T = 330°C下,该源的出气率经测量为5(2)×10 Pa L s,这优化了加载到磁光阱中的原子数量。该源在约1秒内将约10个锂原子加载到阱中。加载后的源重700毫克,适用于许多基于冷原子的可部署传感器。
