摘要
本文主要介绍了氢钟、铷钟、铯钟等几种主要原子频标的物理工作原理、性能、工作与应用领域与研究进展;并将介绍了基于CPT(coherentpopulationtrapping)现象研制的芯片级原子钟;最后简述了原子钟的主要应用需求与发展趋势。
The article mainly discusses the physical principle, performance, working and application fields and recent research development of several main atom frequency standards such as Hydrogen, Rubidium, Cesium atom clock, etc. This part also introduces the chip scale atomic clocks——CSAC based on the CPT （coherent population trapping）. Lastly this article briefly discusses the main application demands and developing trends of atom clock.
