新型原子钟及其在我国的发展

Novel Atomic Clock and Its Development in China

简述了原子喷泉(铯和铷)钟、离子微波钟、原子(离子)光钟、相干布居陷俘(CPT)钟、脉冲激光抽运(POP)铷原子钟以及积分球冷原子钟等新型原子钟的基本原理;概述了这些新型原子钟在我国的研制概况,包括主要方案、特点和进展情况;指出了这种采用激光冷却和陷俘以及新物理原理的新型原子钟具有很高的潜在稳定度和准确度。最后,表明这种新型原子钟,尤其是原子(离子)光钟在我国的发展尚处起步阶段,并对这种新型原子钟在我国的发展提出了建议和评述。

A brief introduction to the novel atomic clocks, including atomic fountain （Cs and Rb） clocks, ion microwave atomic clocks, atomic （ION） optical clocks, coherent population trapping （CPT） atomic clocks and pulsed opticaly pumped （POP） atomic clocks as well as the integrated ball cold atomic clocks, is presented. The basic physics principles of the novel atomic clocks are simply described. The development status of the novel atomic clocks in China, iucluding the basic configurations and features as well as their current reaserch progress, is briefly reviewed. These new standards, which adopt laser cooling and trapping and new physical principles, have excellent potential performences with high-level stability and accuracy. The developments of the new atomic clocks especially the atomic optical clocks in China are in their beginning. And some comments for their developments in China are presented.
