提出一种能处理非高斯非轴对称光束传输的张量方法,引入三个表征任意分布光束的特征张量,运用非对称光学系统的惠更斯衍射积分公式导出了它们的变换规律.讨论了任意光束的质量因子.作为一个实例,分析了高阶厄米-高斯光束通过柱面透镜的变换.

A tensor method is developed in this paper to deal with the propagation of non-Gaussian and non-symmetric optical beams. Three tensors are defined to describe any profile beams. Their transformation rules through non-symmetric systems are derived by using two-dimension Huygens integral. The beam quality factor of arbitrary beam is discussed. As an example, the transformation of high-order Hermite-Gaussian beam through a cylindrical lens system is given.
