摘　　要：采用矢量角谱的方法分析了Airy-Gaussian光束的矢量结构,运用静态相位法得出了光束远场矢量结构的解析表达式.根据得到的TE项和TM项的解析表达式,分别研究了TE项和TM项及整个光束的能流分布.更好地阐明了Airy-Gaussian光束的物理图像,从而为操控光束提供潜在的新方法.Based on the vector angular spectrum of the electromagnetic beam and the method of stationary phase, the analytical vectorial structure of the Airy-Gaussian beam in the far field has been presented. According to the analytical electromagnetic representations of the TE and TM terms, the energy flux distributions of the TE term, the TM term, and the whole beam in the far field are investigated respectively. The formulas obtained are applicable not only in the paraxial case, but also in the nonparaxial case. The physical pictures of Airy-Gaussian beams are well illustrated from the vectorial structure, which may provide a new approach to manipulate laser beams.
