论文摘要
我们在VOIGT几何形状中的磁场中介绍了热$^{87} $ rb原子蒸气的详细光谱研究。我们使用我们的理论模型\ textit {elecsus}拟合了所有Stokes参数的实验光谱，并找到了很好的定量一致性，在所有情况下，RMS误差为$ \ sim 1.5 $ \％。我们从原子信号中提取磁场强度和磁场极化与磁场之间的角度，并测量细胞窗户对光学旋转信号的双折射效应。这使我们能够在高场强和任意几何形状上进行精确的测量，从而进一步开发可能的原子磁力计应用领域。
We present a detailed spectroscopic investigation of a thermal $^{87}$Rb atomic vapour in a magnetic field of 1.5~T in the Voigt geometry. We fit experimental spectra for all Stokes parameters with our theoretical model \textit{ElecSus} and find very good quantitative agreement, with RMS errors of $\sim 1.5$\% in all cases. We extract the magnetic field strength and the angle between the polarisation of the light and the magnetic field from the atomic signal, and we measure the birefringence effects of the cell windows on the optical rotation signals. This allows us to carry out precise measurements at a high field strength and arbitrary geometries, allowing further development of possible areas of application for atomic magnetometers.
