Improvement of the short- and long-term stability of high performance portable optically pumped cesium beam atomic clock
The research of optically pumped cesium beam atomic clock (OPCB) at Peking University has lasted for decades. At present, the short-term frequency stability is 3×10−12/τ and the long-term (5-day) frequency stability can reach 7 × 10−15. The optimization methods of the short-term frequency stability...
