摘要
给出了柱矢量光束的表达式,分析了在近轴近似条件下柱矢量光束的自旋角动量,证明光束的自旋角动量是光子内在的、固有的性质,与光束的偏振态密切相关。
The expression of the cylindrical vector beam has been obtained,and the spin angular momentum in the case of paraxial approximation has been analyzed,it is proved that the spin angular momentum is the intrinsic and inherent nature of photon,which closely related to the polarization state of the beam.
