The principle of laser marker

The "thermal processing" of the laser marker has a laser beam with a higher energy density (it is a concentrated energy flow), which is irradiated on the surface of the processed material. The surface of the material absorbs the laser energy and generates a thermal excitation process in the irradiated area. The temperature of the material surface (or coating) rises, causing phenomena such as metamorphosis, melting, ablation, and evaporation.
