Pulsed optically pumped rubidium atomic clock with optical detection

I. H. Choi, Y.-H. Park, S. H. Lee +3 more

We describe the ongoing work on a87Rb vapor-cell atomic clock using pulsed optical pumping with an optical detection technique. In order to eliminate the light shifts and to increase the stability of vapor-cell atomic clock, pulsed optical pumping technique has been used. For simplicity, direct laser absorption signal is used for the detection of a clock transition.

Frequency stability of a pulsed optically pumped atomic clock with narrow Ramsey linewidth

Haixiao Lin, Jianliao Deng, Jinda Lin +2 more

In general, the linewidth of the Ramsey central fringe (RCF) is equal to 1/(2T), where T is the Ramsey free-evolution time. We demonstrate that the RCF linewidth of a pulsed optically pumped (POP) atomic clock with orthogonal polarization detection based on the magneto-optical rotation effect can be narrowed down to 1/(4T). The Allan deviation of the POP atomic clock decreases from 2.4×10−13τ−1/2 to 1.4×10−13τ−1/2. This corresponds to an improvement in the frequency stability by about 60%. We also estimate the main noise sources that limit the short-term frequency stability of the POP atomic clock.In general, the linewidth of the Ramsey central fringe (RCF) is equal to 1/(2T), where T is the Ramsey free-evolution time.
