Abstract In order to develop a high performance optical pumped Cesium atomic clock, the noise factors affecting the stability of atomic clock are analyzed theoretically. Through quantitative calculation on the various factors influencing the atomic clock short-term stability and long-term stability, the comparison of corresponding experimental results were carred out. Based on analysis of stability limit of the optical pumping atomic clock, a solution on improving the optically pumped Cesium beam atomic clock is proposed, that is a new generation of optically pumped Cesium beam atomic clock design, the stability degree will exceed HP5071 high performance Cesium clock based on magnetic state-selection.
