Measurement of the probe Stark shift of the 87Sr optical lattice clock using the frequency modulation spectroscopy
Qinfang Xu, Xiaotong Lu, Jingjing Xia +2
With the uncertainty of the optical clocks improving to the order of 10-18, the probe light used to detect the clock transition has demonstrated nonnegligible Stark shift, provokin…
