摘要 | We report the Sr-87 optical lattice clock developed at the National Time Service Center. We achieved a closed-loop operation of the optical lattice clock based on Sr-87 atoms. The linewidth of the spin-polarized clock peak is 3.9 Hz with a clock laser pulse length of 300 ms, which corresponds to a Fourier-limited linewidth of 3 Hz. The fitting of the in-loop error signal data shows that the instability is approximately 5 x 10(-15)tau(-1/2), affected primarily by the white noise. The fractional frequency difference averages down to 5.7 x 10(-17) for an averaging time of 3000 s. |
