Abstract

The light shift is a significant error source of optically pumped atomic magnetometers (OPAMs), requiring accurate calculation or measurement to assess its impact on the accuracy of OPAMs. In this paper, a light shift theoretical model considering the gradient of the pump light is established, providing a detailed description of the light shift distribution within the cell under the influence of multiple parameters. Additionally, a light shift measurement method through magneto-optical angle adjustment (MOAA) is proposed, enabling convenient measurement of the light shift. The correctness of the proposed model and the effectiveness of the MOAA method are validated through experiments. The proposed model and method contribute to improving the accuracy of OPAMs and enhancing their performance in practical applications.

光泵浦原子磁强计中光移的建模与测量

光移是光泵原子磁强计（OPAMs）的一个重要误差源，需要精确的计算或测量来评估其对OPAMs精度的影响。本文建立了考虑泵浦光梯度的光移理论模型，详细描述了多参数影响下电池内的光移分布。此外，提出了一种通过磁光角度调整（MOAA）的光移测量方法，方便了光移的测量。通过实验验证了模型的正确性和MOAA方法的有效性。该模型和方法有助于提高OPAMs的精度，提高OPAMs在实际应用中的性能。
