论文摘要
研究了农奴原子磁力计对重复的短脉冲泵的响应。实验观察并理论上解释了盾牌内部磁场的LARMOR频率$ 1/n $的重复速率的量子亚函数。这是一种同步现象。提出了对单个碱原子细胞以及K和RB的混合碱原子进行的研究。在后来，在探针处于另一个通过自旋交换的特定极化时，泵泵。为了解释共振的宽度，研究了自旋破坏，自旋交换和碰撞的影响。该现象的三个水平$λ$模型的量子计算在吸收频谱中的共振频率下显示了脉冲和CW泵模式的偶数，以及EIT的证据。
The response of a SERF atomic magnetometer to a repetitive short-pulsed pump was investigated. Quantum sub-resonances at a repetition rate of $1/n$ of the Larmor frequency of the magnetic field inside the shield are experimentally observed and theoretically explained. This is a type of synchronization phenomenon. Investigations in single alkali atoms cells as well as mixed alkali atoms of K and Rb are presented. In the later, one species is pumped while the probe is on the other specie polarized by spin exchange. The effect of spin destruction, spin exchange and collisions are studied in order to account for the width of the resonances. Quantum calculations of a three levels $Λ$ model for this phenomenon exhibit a dip at the resonance frequency in the absorption spectrum for both cases of pulsed and CW pump modes and an evidence for EIT.
