通过将超冷 Sr-87 限制在神奇波长光学晶格中，我们提出了迄今为止最精确的 S-1(0)-P-3(0) 光钟跃迁研究（2.8 Hz 统计不确定性），并详细分析了 429 228 004 229 869 Hz 绝对频率测量中的系统偏移（19 Hz 不确定性）。高分辨率允许研究光学晶格运动边带结构。该光学原子钟的本地振荡器是稳定的二极管激光器，其赫兹级线宽以倍频程飞秒频率梳为特征。
With ultracold Sr-87 confined in a magic wavelength optical lattice, we present the most precise study (2.8 Hz statistical uncertainty) to date of the S-1(0)-P-3(0) optical clock transition with a detailed analysis of systematic shifts (19 Hz uncertainty) in the absolute frequency measurement of 429 228 004 229 869 Hz. The high resolution permits an investigation of the optical lattice motional sideband structure. The local oscillator for this optical atomic clock is a stable diode laser with its hertz-level linewidth characterized by an octave-spanning femtosecond frequency comb.
