On Miniaturization of Rubidium Atomic Frequency Standard

Abstract
Rubidium atomic frequency standard(RAFS)is being used most popularly,and the miniaturization is the most significant aspect of RAFS.Cavity miniaturizing,circuits digitalizing and special function attaching are the main technical means.Coherent population trap(CPT)is a novel atomic frequency standard which can be built into a chip.Presently,the technique schemes for CPT clock include the traditional programme,adopting micro-electro-mechanical system(MEMS)technique for physical package,and adopting MEMS technique for whole set of device.Following the realization of miniaturization,the atomic frequency standard would face great development.
