Ramsey-coherent population trapping Cs atomic clock based on lin‖lin optical pumping with dispersion detection被引量：2
《Chinese Physics B》2019年第7期174-183,共10页Peng-Fei Cheng Jian-Wei Zhang Li-Jun Wang 
Project supported by the National Key Research and Development Progress of China(Grant No.2016YFA030210);the Initiative Program of the State Key Laboratory of Precision Measurement Technology and Instruments,China
A Cs vapor cell-based atomic clock that uses a lin‖lin pumping scheme with dispersion detection is reported. This atomic clock shows potential for high performance because of its high contrast pumping scheme, and for...

Theoretical analysis of suppressing Dick effect in Ramsey-CPT atomic clock by interleaving lock被引量：1
《Chinese Physics B》2018年第2期280-284,共5页孙晓林 张建伟 程鹏飞 左娅妮 王力军 
Project supported by the National Key Research and Development Program of China(Grant No.2016YFA0302101);the Initiative Program of State Key Laboratory of Precision Measurement Technology and Instruments
For most pulsed atomic clocks, the Dick effect is one of the main limits to reach its frequency stability limitation due to quantum projection noise. In this paper, we measure the phase noise of the local oscillator i...
