我们描述和表征了一个冷铯原子的亚反冲受激拉曼光谱装置。我们特别研究了一种设计用于主动控制和稳定小真空室内冷原子云中的磁场的方法的性能。该装置的性能通过冷铯样品的受激拉曼光谱进行监测。剩余磁场均方根值为300µG，补偿带宽为500赫兹。理论上解释了观测到的光谱的形状，并与数值产生的光谱进行了很好的比较。
We describe and characterize a setup for subrecoil stimulated Raman spectroscopy of cold cesium atoms. We study in particular the performances of a method designed to active control and stabilization of the magnetic fields across a cold-atom cloud inside a small vacuum cell. The performance of the setup is monitored by {em copropagative-beam} stimulated Raman spectroscopy of a cold cesium sample. The root mean-square value of the residual magnetic field is 300 $mu G$, with a compensation bandwidth of 500 Hz. The shape of the observed spectra is theoretically interpreted and compares very well to numerically generated spectra.
