We herein present a theoretical and experimental study on magnetic-field enhanced modulation transfer spectroscopy (MTS) for the 5S (F = 1) → 5P (F' = 0, 1, and 2) transitions of Rb atoms. The density matrix equations are solved numerically to obtain the MTS spectra and an excellent agreement is found between the experimental and calculated results. In particular, the enhancement of the MTS signal for the F = 1 → F' = 0 transition in the presence of the magnetic field is directly verified based on the comparison of the results calculated by neglecting with those calculated including the Zeeman coherences in the F = 1 ground state. The unexpected behaviors of the F = 1 → F' = 1 transition are also examined.
我们在此展示了一项关于铷原子5S（F = 1）→5P（F' = 0、1和2）跃迁的磁场增强调制转移光谱（MTS）的理论和实验研究。通过数值求解密度矩阵方程来获得MTS光谱，并且实验结果与计算结果之间发现了极好的一致性。特别地，基于忽略F = 1基态中塞曼相干的计算结果与包含塞曼相干的计算结果的比较，直接验证了在磁场存在下F = 1→F' = 0跃迁的MTS信号增强。还研究了F = 1→F' = 1跃迁的意外行为。
