摘要
光频移是影响和制约传统的被动式铷频标的稳定度和准确度的主要因素之一。为了减小或消除光频移,通常有两种方法:第一,采用具有相对吸收线中心对称的线型的光源抽运;第二,在时间或空间上将光抽运光检测与微波共振分离。基于光抽运光检测与微波共振在空间上分离的原理,董太乾等提出了分离泡方案。
A new type of separated resonance cell using metal isolating grid is reported, by which we have succeeded in separating the optical pumping and detecting the microwave resonance in passive Rubidium frequency standard. The light shift of the Rubidium frequency standard using this type of separated resonance cell is 15 times smaller than the traditional ones. The temperature characteristics of its wall shift and microwave power shift are also measured and analysed. Further improvement and prospective uses for this type of separated resonance cell are discussed.
