Vector beams (VBs) with potential applications are successfully utilized in many fields as light sources with a spatially-varying polarization profile in recent years. Here, we study the transmission of a VB by manipulating atomic polarization via the optical pumping effect. By using hybridly and radially polarized beams as pump and probe beams in a counter-propagating configuration, we observe a four-petal pattern intensity distribution of probe beam, and the four-petal pattern rotates with the polarization state orientation of the pump beam. The results show a polarization dependent absorption in the atomic media. We experimentally demonstrate the absorption characteristics under different polarization combinations of pump and probe beams. The Jones matrix method is used to explain this phenomenon and the simulations are consistent with the experimental observation. Our results may provide a sound foundation for applications in optical manipulation and quantum information in atomic ensembles.
近年来，具有潜在应用价值的矢量光束（VBs）作为一种具有空间变化偏振分布的光源，已成功应用于许多领域。在此，我们通过光泵浦效应操纵原子偏振来研究矢量光束的传输。通过在反向传播配置中使用混合偏振光束和径向偏振光束分别作为泵浦光束和探测光束，我们观察到探测光束的四瓣图案强度分布，并且该四瓣图案随着泵浦光束的偏振态取向而旋转。结果表明在原子介质中存在偏振相关吸收。我们通过实验证明了泵浦光束和探测光束不同偏振组合下的吸收特性。利用琼斯矩阵方法来解释这一现象，并且模拟结果与实验观测一致。我们的结果可能为原子系综在光学操纵和量子信息方面的应用提供坚实基础。
