论文摘要
我们研究了通过磁场中带有铯蒸气的细胞传播的探针激光束的椭圆噪声射频光谱。实验结果是根据Gorbovitskii和Perel提出的模型来解释的（Opt。Spektrosc。54，388（1983）），根据该模型，观察到的噪声是由于cesium Vapor的光学敏感性的张力$α$散布的光散射出的光的噪声而产生的。我们在实验和理论上都表明，在Larmor频率下，在噪声测量中，以及张张量$α$的反对称性（旋转）部分的波动，可以观察到其对称部分的波动，与线性偏friffercriance（Aligemectrence of Aligrefence（Aligement）的波动相对应）。这些波动提供的极化噪声在频谱上以双层频率定位。
We study radio-frequency spectrum of ellipticity noise of a probe laser beam transmitted through a cell with cesium vapor in a magnetic field. The experimental results are interpreted in terms of the model proposed by Gorbovitskii and Perel (Opt. Spektrosc. 54, 388 (1983)) according to which the observed noise arises due to heterodyning of the light scattered by fluctuations of the tensor $ α$ of optical susceptibility of cesium vapor. We show, both experimentally and theoretically, that, in the noise measurements if this kind, along with fluctuations of the antisymmetric (gyrotropic) part of the tensor $ α$ at the Larmor frequency, may be observed fluctuations of its symmetric part, corresponding to fluctuations of linear birefringence (alignment) of the atomic system. The polarization noise provided by these fluctuations is localized spectrally at the double Larmor frequency.
