对于原子磁力计，如果忽略超精细结构的影响，在某些情况下会导致相当大的测量误差。考虑Cs超精细结构，通过理论推导得到了激励场频率响应的磁共振谱解析形式，并通过实验进行了验证。根据实验方案的结果，找到了具有高分辨磁共振谱的铯原子磁力计的最佳泵浦光频率和强度，并在减小原子磁力计的测量误差和光泵浦研究方面作了进一步的探索。(C)2017爱思唯尔B.V.保留所有权利。
When the influence of hyperfine structure is ignored for atomic magnetometers, it will lead to considerable measuring errors in some cases. Considering the Cs hyperfine structure, an analytical form of magnetic resonance spectrum of the exciting-field frequency response is obtained through theoretical derivation, which is verified by the experiment. Based on the results of the experimental scheme, the optimal frequency and intensity of pump light for a Cs atomic magnetometer with well-resolved magnetic resonance spectrum are found. Additional applications in minimizing the measuring error of atomic magnetometers and the study of optical pumping are explored. (C) 2017 Elsevier B.V. All rights reserved.
