Abstract

We investigate systematic errors associated with a common modulation technique used for phase-sensitive detection of a coherent-population-trapping (CPT) resonance. In particular, we show that modification of the CPT resonance line shape due to the presence of off-resonant fields leads to frequency shifts that may limit the stability of CPT-based atomic clocks. We also demonstrate that an alternative demodulation technique greatly reduces these effects.

  15. For this series of measurements, we used a vapor cell with isotopically enriched 87Rb and 22 Torr of Ne buffer gas. The change in buffer gas leads to both a different overall clock frequency shift and a narrower CPT resonance than the 5 Torr N2 cell we used for the other measurements we report here.
