COMSOL uses the Ray Optics Module to simulate Gaussian beam propagation

Please login with a confirmed email address before reporting spam

When simulating an optical system using COMSOL, the heating effect of the laser on the device needs to be considered due to the large laser power. However, the Wave Optics Module of COMSOL is computationally intensive and complex for calculating the optical-mechanical-thermal effects of complex optical systems, so the use of ray optics to trace the laser propagation is considered for simulation. The Gaussian beam is used for the experiment, and the correlation simulation of the Gaussian beam by COMSOL is mainly found in the Wave Optics Module, so I asked how to use the Ray Optics Module to construct a Gaussian light source and model the propagation of Gaussian beams in the optical system?
