| Abstract: | In this paper,the working principle of CPT atomic clock is briefly introduced.Two key indicators of atomic frequency standard are discussed,which are short-term stability and frequency drift.The frequency locking servo control circuit of the CPT atomic clock is systematically analyzed and optimized designed by using a saturation absorption experiment to verify the control system,we get a long time frequency stability reached 1.6×10^-12 in 100s. It is expected to further improve the frequency stability. |
