摘要:

提出了一种改进的磁光致旋转(MOR)效应探测方案,其中线偏振激光场与积分球中的冷$^{87}$ Rb原子相互作用.实验中检测了探测光偏振面的旋转角度。结果表明,偏置磁场、探测光强度和失谐量以及冷原子温度是影响MOR效应的关键参数。该方案可以提高旋转信号的对比度,为高对比度冷原子钟和磁强计提供了一种有用的方法。

英文摘要:

We present a modified scheme for detection of the magneto-optical rotation (MOR) effect, where a linearly polarized laser field is interacting with cold $^{87}$Rb atoms in an integrating sphere. The rotation angle of the probe beam's polarization plane is detected in the experiment. The results indicate that the biased magnetic field, the probe light intensity and detuning, and the cold atoms' temperature are key parameters for the MOR effect. This scheme may improve the contrast of the rotation signal and provide an useful approach for high contrast cold atom clocks and magnetometers.
