轴对称光束被定义为这样的光束，其中坡印廷矢量在传播方向上的分量不依赖于适当选择的坐标系中的方位角以揭示光束的对称性质。它示出，这样的光束被编码在一组的光束形状系数gn，然而，定义在一个更一般的方式比通常的情况下的高斯光束。研究了这类光束的分波展开及其性质。
Axisymmetric light beams are defined as light beams for which the component of the Poynting vector in the direction of propagation does not depend on the azimuthal angle in suitably chosen coordinate systems to reveal the symmetric property of the beam. It is shown that such beams are encoded in a set of beam-shape coefficients gn that are, however, defined in a more general way than usual in the case of Gaussian beams. Partial-wave expansions and properties of such beams are studied.
