Frequently laser heating is modeled by solving the heat transfer equation under the assumption of a heat source profile applied to the surface. In that approach, you only solve the heat transfer equation, subject to the assumed thermal load. This keeps the model quite simple, and suitable when the material is opaque at the wavelength in question.

By combining the Heat Transfer Module with other add-ons from the COMSOL ® product suite, you can create advanced heat transfer simulations. The possible multiphysics phenomena include thermal contact, nonisothermal turbulent flow, heat transfer in porous media, Joule heating, microwave heating, and laser heating.

Jun 15, 2017 · A laser may stop working after it is turned on or pumped harder. This is due to the thermal lensing effect. The laser crystal is pumped by another light source or sources to cause the inversion population. This process generates undesired heat by the residual energy of the pump light that is not used to induce the stimulated emission.

Laser ablation or photoablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma.
