Theoretical analysis and numerical simulation show that the method can optimize the stability AFS which is related with d. And is the duty of phase-discriminating of AFS. If in-loop noise possesses white frequency noise characteristics, the stability will decrease following the coefficient of root(1-d). Specially, when d approaches to 1, the stability will reach the limit of quantum project noise. Here we demonstrate three schemes to realize the idea in experiments and overlap-feedback is the most easily implemented one. Considering Dick effect in our method, the stability of our atomic fountain will be better than 1 x 10(-14) tau(-1/2) at d > 0.93.2017 JOINT CONFERENCE OF THE EUROPEAN FREQUENCY AND TIME FORUM AND IEEE INTERNATIONAL FREQUENCY CONTROL SYMPOSIUM (EFTF/IFC)Improving the frequency stability of atomic frequency standard basing on the noise asynchromism correction会议论文EnglishWang, Qian; Wei, Rong; Dong, Richang; Lin, Jinda; Wang, Wenli; Wang, Yuzhu43484 WOS:000431392100082
