Precise calibration of zero-crossing temperature and drift of an ultralow expansion cavity with a clock transition spectrum被引量:1
《Chinese Physics B》2018年第5期150-154,共5页Hui Liu Kun-Liang Jiang Jin-Qi Wang Zhuan-Xian Xiong Ling-Xiang He Bao-Long Lu 
Project supported by the National Natural Science Foundation of China(Grant Nos.61227805,11574352,91536104,and 91636215);the Strategic Priority Research Program of the Chinese Academy of Sciences(Grant No.XDB21030100)
We report a clock transition spectrum approach,which is used to calibrate the zero-crossing temperature and frequency drift of an ultralow expansion(ULE)cavity with a Hertz level resolution.With this approach,the line...

Frequency locking of a 399-nm laser referenced to fluorescence spectrum of an ytterbium atomic beam
《Chinese Optics Letters》2014年第2期34-37,共4页龙云 熊转贤 张曦 张梦娇 吕宝龙 贺凌翔 
supported by the National Natural Science Foundation of China(Nos.11274349,11204353,and 61227805);the National Key Basic Research and Development Program(973)of China(No.2011CB921503)
The laser cooling of ytterbium(Yb) atoms needs a 399-nm laser which operates on the strong1S0-1P1 transition and can be locked at the desired frequencies for different Yb isotopes.We demonstrate a frequency locking ...
