The processing principle of co2 laser marker CO2 laser marker is a gas laser machine whose frequency band wave length of infrared light is 10.64um. CO2 gas is filled in the discharge tube as the medium to produce laser. When high voltage is added to the electrode, it will produce glow discharge in the discharge tube and then the gas molecule will discharge laser. After the energy of laser is strengthened, it will form the laser beams to process the materials. Computer-controlled resonance mirror can change the path of the laser beams so that automatic marking can be accomplished. Characteristics of the marking machine Large laser power.Power controlled by software?can be adjusted.The cost of the process is low with no consuming materials.Large marking scope, the mark is clear and not easily destroyed. Good cutting effeciency. Marking depth can be controlled at will.Suitable for many products.
