The nonlinear magneto-optical rotation (NMOR) atomic magnetometer is a highly sensitive total-field device with significant applications in fundamental physics, geophysics, and biomedical monitoring. The atomic polarization, which is optically induced through resonant light pumping, plays a pivotal role in determining the sensitivity and stability of the magnetometer. In this paper, refined analysis and representation of atomic polarization in NMOR atomic magnetometers are presented through the establishment of a three-dimensional polarization distribution model based on the rate equation. The polarization characteristics of the single-beam pump and repump modes are compared, and the scale factors of both modes are experimentally measured. Both simulation and experimental results demonstrate that the proposed model accurately captures the spatial distribution of optically induced polarization, which is essential for improving the performance and extending the application potential of NMOR magnetometers in high-sensitivity optical sensing systems.
