In this work, it is used the Geometry and Tracking (Geant4) software package (version 4.9.4) to simulate the passage of light through the human eye, which is an object-oriented toolkit for the simulation of particle propagation through matter . It makes use of a large number of physics models to simulate radiation transport of various particles ... Modifying the laser beam profiles can help with the stability of the melt pool dynamics in different laser welding processes. In FLOW-3D WELD, it is possible to simulate various beam profiles such as top hat, Gaussian, ring, donut, or any arbitrary shapes and distributions of the laser heat flux.
reZonator reZonator is a powerful software for designing laser resonators and calculation the propagation of light beams (as gaussian so as ray vectors) in complex optical systems. It has a modern, user-friendly interface, so you need no specialized training or programming skills to use all of its functions and tools.
