A numerical model of Gaussian beam propagation in planar Fabry-Perot (FP) etalons is presented. The model is based on the ABCD transfer matrix method. This method is easy to use and interpret, and readily connects models of lenses, mirrors, fibres and other optics to aid simulating complex multi-component etalon systems. To validate the etalon model, its predictions were verified using a previously validated model based on Fourier optics. To demonstrate its utility, three different etalon systems were simulated. The results suggest the model is valid and versatile and could aid in designing and understanding a range of systems containing planar FP etalons. The method could be extended to model higher order beams, other FP type devices such as plano-concave resonators, and more complex etalon systems such as those involving tilted components.
提出了一种用于平面法布里-珀罗（FP）标准具中高斯光束传播的数值模型。该模型基于ABCD 传输矩阵方法。该方法易于使用和解释，并且可以轻松地将透镜、镜子、光纤和其他光学器件的模型连接起来，以帮助模拟复杂的多组件标准具系统。为了验证标准具模型，使用先前基于傅里叶光学验证的模型来验证其预测。为了展示其用途，模拟了三个不同的标准具系统。结果表明，该模型有效且通用，可以帮助设计和理解包含平面 FP 标准具的一系列系统。该方法可以扩展到模型更高阶的光束、其他 FP 类型的器件，如平凹谐振器，以及更复杂的标准具系统，如涉及倾斜组件的系统。
