| Popis: | We report the realization of closed-loop operation of an optical lattice clock based on 171Yb atoms. We interrogate the clock transition using single Rabi pulses of 578 nm laser light. The two π-transitions from ground states are alternatively interrogated, and the clock laser frequency is locked to the center of the two resonances. The in-loop error signal stability of the clock reaches for an average time of 3500 s. We also perform interleaved operations of the clock with two independent servo loops, and the fractional frequency difference averages down to in 7200 s. |
