Comprehensive simulation of laser processing systems: from source to surface interaction

The precision and efficiency of laser-enabled material processing are influenced by the laser beam and its interaction with the material. Optimizing system parameters remains complex due to the interplay between the laser source, optics, and material, requiring extensive trial and error. We present an advanced simulation framework modeling the entire laser processing system, from the laser source to the material interaction. Using COMSOL, LAMMPS, and in-house code, the simulation is calibrated with our experimental laser system. The framework accounts for various system parameters, predicting the impact of configurations on the laser beam and machining process. We simulate the interaction of a laser pulse with the material, providing insights into pulse effects. This comprehensive simulation enhances understanding of laser-matter interactions and optimizes system configurations, improving precision and efficiency. Our framework streamlines the development of laser processing systems, accelerating innovation and benefiting various industries.
