Abstract

We apply the multi-pole magnet to the optical pumped cesium atomic clock, which can focus the pumped cesium atoms before entering the microwave cavity. By reducing the spatial divergence of cesium atomic beam as well as the loss of magnetic state selection of cesium atoms, this system can improve the utilization efficiency of cesium atoms in cesium atomic clock by an order of magnitude. Thus the signal-to-noise ratio and the stability index of cesium clock can be improved.

A new magnetic state selection method in high-performance optically detected compact cesium beam clocks

Sifei Chen, Chen Liu, Lifeng Fan +4 more

We perform a new scheme of magnetic state selection in optically detected compact cesium beam clocks. Unlike the conventional method, we select atoms in the ground state |F = 4, mF ≠ -4⟩ by pointing the atomic collimator to the convex pole of the magnet realizing the two-wire magnetic field and detect atoms in |F = 3⟩ after interacting with the microwave field using a distributed feedback laser. The fluorescence background is greatly reduced as the inherent residual atoms |F = 4, mF = -4⟩ are avoided in this reversed scheme. The velocity distribution is narrowed, and the most probable velocity is decreased, since atomic trajectories are close to the weak-field region. We also investigate the relationship between the position of the atomic collimator and the distributions of the atomic beam, which is consistent with the Monte Carlo-based simulation model. By applying the reversed scheme and setting the deviated position of the collimator to 1.3 mm, the signal contrast is improved from 0.7 to 3, and the short-term frequency stability reaches 3.0 × 10-12 τ-1/2, nearly three times better than that of the high-performance version of Microsemi 5071A.

Preliminary progress of the state preparation with a new optical pumping method in a cesium atomic fountain clock

Lei Han, Fang Fang, Yani Zuo +5 more

In this paper, a new optical pumping method, redistributing the atom populations among the Zeeman magnetic sublevels of the ground state |F=3> is proposed as the state preparation process to improve the signal to noise ratio (SNR) of the atomic fountain clock with a larger atom population on the |F=3, mF=0>clock state. A preliminary experimental result of state preparation efficiency exceeding 60% is obtained on the NIM6 cesium (Cs) fountain clock.

Compact CW cold beam cesium atomic clock

Walter F. Buell, Bernardo Jaduszliwer

We present a novel cesium beam physics package, which uses optical techniques to combine the high signal-to-noise ratios achievable by optical pumping and beam brightening with the narrow linewidth allowed by a slow atomic beam. Our design can be realized in a compact, robust package suitable for space applications. Our approach differs from other laser-cooled clocks in that we use a cold-atom source that provides a continuous beam. We estimate the shot noise-limited stability that can be achieved with this physics package to be two to three orders of magnitude better than that of current compact cesium beam atomic clocks.

Optical state selection process with optical pumping in a cesium atomic fountain clock*

Lei Han, Fang Fang, Weiliang Chen +5 more

We propose and realize a new optical state selection method on a cesium atomic fountain clock by applying a two-laser 3–3′ optical pumping configuration to spin polarize atoms. The atoms are prepared in |F = 3, mF = 0〉 clock state with optical pumping directly after being launched up, followed by a pushing beam to push away the atoms remaining in the |F = 4〉 state. With a state selection efficiency exceeding 92%, this optical method can substitute the traditional microwave state selection, and helps to develop a more compact physical package. A Ramsey fringe has been achieved with this optical state selection method, and a contrast of 90% is obtained with a full width half maximum of 0.92 Hz. The short-term frequency stability of 6.8 × 10−14 (τ/s)−1/2 is acquired. In addition, the number of detected atoms is increased by a factor of 1.7 with the optical state selection.

An optically pumped atomic clock based on a continuous slow cesium beam

Weibin Xie, Qing Wang, Xuan He +8 more

Herein, we report the scheme of an optically pumped atomic clock based on a cold cesium atomic beam source. We propose the laser system and physical mechanism of this atomic clock, wherein the atomic beam travels in an upper parabolic trajectory, thereby eliminating the light shift effect. In the experiments, when the length of the free evolution region was 167 mm, the line width of the Ramsey fringe was 37 Hz. When the expected signal-to-noise ratio of the Ramsey fringe that can be achieved is 36,000, the expected short-term frequency stability is about 3.6 × 10–14/√τ, which is significantly higher than that of a conventional optically pumped cesium clock of similar volume.

Improvement of the short-term stability of atomic fountain clock with state preparation by two-laser optical pumping*

Lei Han, Fang Fang, Weiliang Chen +4 more

To improve the signal to noise ratio (SNR) and the short-term stability of cesium atomic fountain clocks, the work of two-laser optical pumping is presented theoretically and experimentally. The short-term stability of the NIM6 fountain clock has been improved by preparing more cold atoms in the | F = 4, mF = 0〉 clock state with a shortened cycle time. Two π-polarized laser beams overlapped in the horizontal plane have been applied after launching, one is resonant with | F = 4〉 → | F′ = 4〉 transition and the other is resonant with | F = 3〉 → | F′ = 4〉 transition. With optical pumping, the population accumulated in the | mF = 0〉 clock state is improved from 11% to 63%, and the detection signal is increased by a factor of 4.2, the SNR of the clock transition probability and the short-term stability are also improved accordingly.
