频率梳在基础物理及多个领域的实际应用中广泛使用。本文报道了在铷-氙混合气体自旋系统中，利用脉冲调制自旋激射器实现超低频磁频率梳。该磁频率梳的频谱分布主要取决于脉冲持续时间、反馈场的强度和相位偏移。我们基于自旋回波链给出了一个简单的理论模型，该模型与实验结果吻合良好。该磁频率梳工作在超低频范围内，频率分辨率可达数十纳赫兹。
英文摘要
Frequency combs are widely used in fundamental physics and practical applications at various areas. Here we report the realization of an ultralow frequency magnetic comb using a pulse modulated spin maser in the Rb-Xe hybrid gaseous spin system. The magnetic frequency comb has a spectral distribution depending mainly on the pulse duration, the strength and phase shift of the feedback field. A simple theoretical model is given in terms of the spin echo chain and agrees well with the experimental results. The magnetic frequency comb works in an ultralow frequency range and reaches a frequency resolution down to tens of nanohertz.
