研究了磁场梯度作用下镀膜Rb蒸气室中电磁感应透明（EIT）的线宽。观察到EIT线宽随磁场梯度的非线性展宽。结果发现，在较高的激光强度和较大的光束尺寸的场梯度的运动平均更明显。在相同的制度下，有一个小的线宽减小磁场梯度的增加。我们建立了一个蒙特-卡罗模型，其结果与我们的实验定性一致。提出了上述现象的物理图象。这些结果提供了一个运动平均下的EIT线宽行为的理解，并应是有用的应用在量子光学和计量学的基础上涂敷蒸汽细胞。
The linewidth of electromagnetically induced transparency (EIT) in a coated Rb vapor cell was studied under a magnetic field gradient. The nonlinear broadening of the EIT linewidth with the magnetic field gradient was observed. It was found that the motional averaging of the field gradient was more pronounced at higher laser intensities and larger beam sizes. In the same regime, there was a small linewidth decrease with the increasing magnetic field gradient. We have established a Monte-Carlo model, which gave results in good qualitative agreement with our experiment. Physics pictures for the above phenomena were also suggested. These results provide an understanding of the EIT linewidth behavior under motional averaging, and should be useful for applications in quantum optics and metrology based on coated vapor cells.
