我们提出了一个定量的，系统的研究极化的塞曼磁亚级的金刚石的nv缺陷作为一个函数的磁场对准相对于nv缺陷轴。实验室框架中nv偏振的取向依赖是由一个恒定缺陷框架偏振的维格纳旋转来解释的。我们还发现，nv缺陷能级的偏振度随P1缺陷浓度的变化而变化，当P1浓度从20 ppm变化到100 ppm时，样品中m(s) = 0态的光泵浦偏振度分别从46%下降到36%。
We present a quantitative, systematic study of the polarization of the Zeeman magnetic sublevels of the NV-defect in diamond as a function of magnetic field alignment relative to the NV-defect axis. The orientation dependence of NV-polarization in the lab frame is accounted for by a Wigner rotation of a constant defect frame polarization. We also find that the NV-defect level polarizations vary with the P1 defect concentration, and that the polarization of the m(s) = 0 state with optical pumping decreases from 46% to 36% in samples as P1 concentrations vary from 20 ppm to 100 ppm, respectively.
