Abstract:
We report on the current status of our pulsed optically pumped (POP) Rubidium (Rb) double resonance (DR) micro-cell atomic frequency standard. An estimation of the limiting parameters to the short-term stability is given, including the relatively high relaxation rates in the microcell employed. The stability measured beyond 104 seconds of integration time is < 2e-12. In particular, in POP operation the light-shift effect is reduced by at least two order of magnitude compared to continuous mode.
