What is the principle of CO2 laser marking machine
The CO2 laser marking machine realizes automatic marking by changing the optical path of the laser beam through the computer-controlled galvanometer. That is, when the laser beam is irradiated on the surface of the material, the light energy is instantly converted into heat energy, and the surface of the material is instantly melted or even vaporized, thereby forming a mark.
