We demonstrate that the lin-par-lin Ramsey coherent population trapping Rb clock using a dispersion detection technique has a promising performance. We theoretically and experimentally investigate the signal-to-noise ratio of the Ramsey spectrum signal by varying the relative angle of the polarizer and analyzer as well as the magnetic field. Based on the experimental results, the optimized relative angle and magnetic field are determined. This kind of atomic clock is attractive for the development of compact, high performance vapor clock based on CPT.
我们证明，使用色散检测技术的线性-平行-线性拉姆齐相干布居囚禁铷原子钟具有良好的性能。我们通过改变偏振器和分析器的相对角度以及磁场，从理论和实验上研究了拉姆齐谱信号的信噪比。基于实验结果，确定了优化的相对角度和磁场。这种原子钟对于基于相干布居囚禁的紧凑型高性能蒸汽钟的发展具有吸引力。
