We report a demonstration of vapor-phase Rubidium (Rb) density stabilization in a vapor cell using a solid-state electrochemical Rb source device. Clear Rb density stabilization is observed. Further demonstrations show that the temperature coefficient for Rb density can be reduced more than 100 times when locked and the device's power consumption is less than 10 mW. Preliminary investigation of the locking dynamic range shows that the Rb density is well stabilized when the initial density is five times higher (33 × 10 /cm) than the set point density (6 × 10 /cm). Active stabilization with this device is of high interest for portable cold-atom microsystems where large ambient temperature working ranges and low power consumption are required.
我们报告了一项利用固态电化学铷源装置在蒸汽池中实现气相铷（Rb）密度稳定的演示。观察到铷密度的明显稳定。进一步的演示表明，锁定时铷密度的温度系数可降低100倍以上，且该装置的功耗小于10毫瓦。对锁定动态范围的初步研究表明，当初始密度比设定点密度（6×10/cm）高五倍（33×10/cm）时，铷密度能很好地稳定下来。对于需要大环境温度工作范围和低功耗的便携式冷原子微系统而言，使用该装置进行主动稳定具有很高的价值。
