本文提出了一种在近轴近似下模拟光学激光系统的新方法，并特别应用于干涉引力波探测器。这里提出的方法是基于厄米-高斯横模的激光场的标准分解。创新的功能包括一个符号操作的方程描述的领域传播。这种方法可以大大减少计算时间，特别是当需要大量的高阶模式来正确模拟系统时。新算法已在一个名为MIST的开源工具箱中实现，该工具箱基于MATLAB®环境。MIST已经开发出来，并正在用于高级引力波探测器的设计框架中。将讨论来自该应用领域的示例，以说明仿真工具的能力和性能。
This paper presents a new approach to the simulation of optical laser systems in the paraxial approximation, with particular applications to interferometric gravitational wave detectors. The method presented here is based on a standard decomposition of the laser field in terms of Hermite–Gauss transverse modes. The innovative feature consists of a symbolic manipulation of the equations describing the field propagation. This approach allows a huge reduction in the computational time, especially when a large number of higher order modes is needed to properly simulate the system. The new algorithm has been implemented in an open source toolbox, called the MIST, based on the MATLAB® environment. The MIST has been developed and is being used in the framework of the design of advanced gravitational wave detectors. Examples from this field of application will be discussed to illustrate the capabilities and performance of the simulation tool.
