Abstract

When frequency modulation is used to detect coherent population trapping resonances, shifts proportional to the modulation parameters and the laser detuning from the excited state are observed. These shifts limit the stability of CPT-based atomic clocks.

Modulation-induced frequency shifts in a coherent-population-trapping-based atomic clock

David F. Phillips, Irina V. Novikova, Christine Y.-T. Wang +2 more

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.

Active light shift stabilization in modulated CPT clocks.

We demonstrate a simple technique to significantly improve the long-term frequency stability in atomic clocks based on coherent population trapping (CPT). In this technique, a servo is used to control the local oscillator power level in such a way that the optical spectrum generates no net light shift. This ensures that the clock frequency is always given by the atomic resonance frequency that is not perturbed by the incident light fields.

A compact setup for double-modulation coherent population trapping clock

Peter Yun, François Tricot, David Holleville +2 more

We demonstrate an atomic clock based on double-modulation CPT. With a high contrast CPT signal observed in this scheme, we get a preliminary result of the frequency stability: 4×10-13 at 1 second. It shows the possibility to implement an atomic clock with a compact and robust setup while still maintaining its high performance.

Light shift in modulated coherent population trapping atomic clocks

Ke Deng, Tao Guo, Juan Su +3 more

We have studied the light shift in coherent population trapping (CPT) atomic clocks under full band modulation (FBM) and under half band modulation (HBM). The theoretical results show that the light shift under FBM is only 1/4 of the light shift under HBM. Our experimental results confirm the theoretical results. Therefore, we can easily improve the stability of CPT clocks by replacing HBM with FBM.

Frequency shift caused by the line-shape asymmetry of the resonance of coherent population trapping

Valeriy I. Yudin, M. Yu. Basalaev, А. В. Тайченачев +5 more

We theoretically study the frequency shift in atomic clocks caused by the line-shape asymmetry of coherent population trapping (CPT) resonance in a bichromatic laser field. This asymmetry arises due to the inequality of the resonant spectral components and nonzero one-photon detuning. The line-shape-asymmetry-induced shift depends on the intensity of the resonant fields, which leads to a degradation in long-term stability due to fluctuations of the laser field parameters. A frequency stabilization based on the harmonic modulation of two-photon detuning is considered. It is shown that the use of a high-frequency modulation (compared to the CPT resonance width, i.e., the Pound-Drever-Hall regime) makes it possible to significantly suppress this shift (by one to two orders of magnitude).
