本文介绍了一般像散高斯光束的完备模型，作为高斯光束在基模中的最一般情况。这包括传播、反射和折射的规律，以及从复值光束描述中提取其实值参数（如光束光斑半径和波前曲率半径）的方程。所提出的模型适用于光束斜入射到任何三维表面的情况，这种情况可以用入射点的二阶方程来近似。因此，它可以用于模拟各种各样的三维光学系统。模型的实验验证与仿真结果吻合较好。(C) 2013年美国光学学会
The paper introduces the complete model of the general astigmatic Gaussian beam as the most general case of the Gaussian beam in the fundamental mode. This includes the laws of propagation, reflection, and refraction as well as the equations for extracting from the complex-valued beam description its real-valued parameters, such as the beam spot radii and the radii of curvature of the wavefront. The suggested model is applicable to the case of an oblique incidence of the beam at any 3D surface that can be approximated by the second-order equation at the point of incidence. Thus it can be used in simulations of a large variety of 3D optical systems. The provided experimental validation of the model shows good agreement with simulations.
