Comsol laser heating, In addition, the wafer itself is rotated on its stage

Comsol laser heating, In some cases, coupling between different physics might be necessary. This series of tutorials show how to simulate laser heating of glass. In addition, the wafer itself is rotated on its stage. The scenarios investigated are: Stationary laser with constant power – CW mode Stationary laser with pulsed power – Pulsed mode The heating profile does introduce some significant temperature variations, because the laser deposits the same amount of heat over a larger total swept area when it is focused at the outside of the wafer. The transient thermal response of the wafer is shown. The incident heat flux from the laser is modeled as a spatially distributed heat source on the surface. The heating due to laser is treated as a body heat source. Learn how to use COMSOL Multiphysics® for specific application areas. An interesting modification to this example would be to investigate alternative heating profiles for smoother heating. For thermal effects, you might use the Heat Transfer Module. For structural changes, consider the Structural Mechanics Module. The peak, average, and minimum temperature during the heating process is computed, as well as the . 4, was used to create a 2D transient heat transfer time-dependent model to simulate the temperature distribution and the laser heating of the A301 steel baseplate surface and determine the effect of temperature on the optimization process of the alloys. When light is incident upon a semitransparent material, some of the energy will be absorbed by the material itself. If we can assume that the light is single wavelength, collimated (such as from a laser), and experiences very minimal refraction, reflection, or scattering within the material itself, then it is appropriate to model the light intensit Jan 3, 2023 · In this blog post, we cover how to model the heating of a semitransparent material using the Beer–Lambert law. In this video, you learn how to model a moving laser heat source (pulsed and continuous wave mode) in COMSOL Multiphysics. Jan 1, 2022 · Comsol Multiphysics 4. The study captures temperature variations, hotspot formation, and thermal gradients induced by a moving Gaussian laser beam, which is relevant for semiconductor wafer processing and materials engineering. An interesting modification to this model would be to investigate alternative heating profiles for smoother heating. A silicon wafer is heated up by a laser that moves radially in and out over time. A silicon wafer is heated up by a laser that moves radially in and out over time. Jun 22, 2015 · In this blog post, learn how to model laser-material interactions and heating in COMSOL Multiphysics with a range of different approaches. Browse the COMSOL Learning Center for self-paced courses and articles. The heating profile does introduce some significant temperature variations, because the laser deposits the same amount of heat over a larger total swept area when it is focused at the outside of the wafer. Jun 26, 2025 · COMSOL offers various physics interfaces that can be combined to simulate laser-material interactions.
