CO2 laser to CO2 gas as the medium, the CO2 and other auxiliary gas into the discharge tube, in the electrode with high pressure, the discharge tube glow discharge, the gas released by the wavelength of 10.64um laser, the laser energy amplification, the vibration Mirror scanning and F-Theta mirror focus, in the computer, and laser marking control card, under the control of the workpiece, according to the user’s request for images, text, numbers, lines of the mark.

2. Laser tube

CO2 glass tube laser marking machine: the use of CO2 glass tube laser, which is a long generation of products, has been widely used; but it has a drawback: CO2 glass tube laser life of only 5000 hours, not very good to meet the large quantities produce.

Co2 metal tube marking machine: the metal tube is used wildly in recent years, comparing with the glass tube ,its longevity is longer.
