将Ca时钟跃迁(s1 /2- d5 / 2,729 nm)与Sr光晶格时钟跃迁(S0P0, 698nm)进行了频率比较,得出Ca / Sr的频率比为0.957 631 202 358 049 9(23)。光学比较的快速特性使得频率比的统计不确定度在1000秒内达到1×10,并且得出的值与使用国际原子时(TAI)链路进行的单独绝对频率测量计算的值一致。光学比较得到的频率比的总不确定度(不含微波链路不确定度)比绝对频率测量得到的频率比的总不确定度小,显示了光学频率评估的优势。我们报告了Ca的绝对频率,系统不确定度比我们以前的测量[1]小14倍。参考文献和链接K.

Optical frequency comparison of the Ca clock transition Ca (S1/2-D5/2, 729nm) against the Sr optical lattice clock transition Sr (S0P0, 698nm) has resulted in a frequency ratio Ca / Sr = 0.957 631 202 358 049 9(2 3). The rapid nature of optical comparison allowed the statistical uncertainty of frequency ratio Ca / Sr to reach 1×10 in only 1000s and yielded a value consistent with that calculated from separate absolute frequency measurements of Ca using the International Atomic Time (TAI) link. The total uncertainty of the frequency ratio using optical comparison (free from microwave link uncertainties) is smaller than that obtained using absolute frequency measurement, demonstrating the advantage of optical frequency evaluation. We report the absolute frequency of Ca with a systematic uncertainty 14 times smaller than our previous measurement [1]. References and links 1. K. Matsubara, K. Hayasaka, Y. Li, H. Ito, S.
