What is the principle of the CO2 laser marking machine?

The CO2 laser marking machine is suitable for high-speed laser marking of PVC, PE, PET shrink sleeves, easy-to-tear lines of shrink labels, and laser marking of some flexible packaging air holes. Compared with traditional mechanical processing methods, the CO2 laser marking machine has the advantages of fast processing speed, long life, good aperture uniformity, and high precision. Then, let's introduce in detail what is the principle of the CO2 laser marking machine?

CO2 laser marking machine composition

CO2 laser marking machine is mainly composed of CO2 laser, objective lens, beam expanding mirror, scanning vibrator, control computer, CO2 laser power supply, laser control card, laser frame, laser circulating water system, laser control software, circuit control system, etc.

Working principle

The CO2 laser marking machine is the carbon dioxide laser marking machine. It is a laser vibrator marking machine, the CO2 gas as the working medium. The CO2 laser marking machine is a laser vibrator marking machine with CO2 gas as the operation intermediary. The CO2 laser in the CO2 laser marking machine uses CO2 gas as the medium. CO2 and other auxiliary gases are charged into a discharge tube and a high voltage is applied to the electrode. A glow discharge is generated in the discharge tube, which causes the gas to release a laser with a wavelength of 10.64um. Users can make numbers and lines on the workpiece according to their own requirements.

Main features

The CO2 laser marking machine uses a carbon dioxide laser, which is a general-purpose model, with a rear focus mode, small size, and high integration. This CO2 laser marking machine is suitable for marking most non-metallic materials, such as paper packaging, plastic products, non-metallic labels, leather fabrics, glass ceramics, resin plastics, bamboo and wood products, PCB boards, etc. The CO2 laser marking machine is a gas laser with a wavelength of 10.64um in the far-infrared light band. It uses CO2 gas to be charged into the discharge tube as the medium for generating laser light. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube to make it the gas molecules release laser light.

The CO2 laser marking machine is a gas laser marking machine with a wavelength of 10.6μm, which belongs to the mid-infrared frequency band. The CO2 laser has relatively large power and relatively high electro-optical conversion efficiency. At present, it is mainly used for engraving non-metal and some metal materials. It is widely used in food packaging, beverage packaging, pharmaceutical packaging, architectural ceramics, clothing accessories, craft gifts, notebook and flat shells, wire stripping, film cutting, shell nameplates, etc.
