CO2 laser marking machine is a gas laser machine whose frequency band wave length of infrared light is 10.64nm, CO2 gas is filled in the discharge tube as th emedium to produce laser, when high voltage is added to the electrode, it will produce glow discharge in thedischarge tube and then the gas molecule will discharge laser, after the energy of laser is strengthed it will form the laser beam to produce. Computer controlled resonance nirror can change the path of the laser beam so that automatic marking can be accomplished.
