摘要
本文研究了由非对称拉盖尔高斯(aLG)光束控制的四能级双V原子系统的特性。在探测场的传输过程中,发生了圆形双折射,为矢量光束的形成提供了条件(VBs),并且重点讨论了探针场强度和偏振随传输距离的变化。结果表明,探测场的偏振在短距离内呈线性变化。此外,证明了传输距离的操纵可以实现探测场的偏振分离。这为获得VB提供了一种新的思路。
In this paper, the properties of a four-level double-V atomic system controlled by asymmetric Laguerre Gaussian (aLG) beam are studied. During the transmission of the probe field, circular birefringence occurs, resulting in vector beams (VBs). The variation of probe field intensity and polarization with transmission distance is discussed emphatically. The results show that the polarization of the probe field varies linearly over a short distance. In addition, it has been proved that the operation of transmission distance can achieve polarization separation of the probe field. This provides a new method for obtaining VBs.
