A method is developed for deducing the required source in the complex space for the full-wave generalization of a specified paraxial beam. This method is applicable to all paraxial beams. However, the details of the method are presented for the anisotropic Gaussian beam. The required source in the complex space for the anisotropic Gaussian beam is a line source with a Gaussian distribution. An expression is derived for the anisotropic Gaussian full wave, which in the appropriate limit reproduces the anisotropic Gaussian paraxial beam. The radiation intensity of the anisotropic Gaussian light wave is determined; its characteristics are analyzed and compared with those of the limiting case of the anisotropic Gaussian paraxial beam.
开发了一种方法，用于推导复空间中特定傍轴光束全波推广所需的源。该方法适用于所有傍轴光束。然而，这里针对各向异性高斯光束给出了该方法的详细内容。各向异性高斯光束在复空间中所需的源是具有高斯分布的线源。推导了各向异性高斯全波的表达式，在适当极限下该表达式可重现各向异性高斯傍轴光束。确定了各向异性高斯光波的辐射强度；分析了其特性，并与各向异性高斯傍轴光束的极限情况的特性进行了比较。
