Principle application of CO2 laser marking machine


The principle of CO2 laser marking machine, CO2 laser marking machine is CO2 laser marking machine (CO2 is carbon dioxide). It is a laser galvanometer marking machine that uses CO2 gas as working medium. CO2 laser marking machine is a CO2 laser with CO2 gas as the medium. CO2 and other auxiliary gases are charged into the discharge tube to add high voltage to the electrode. The discharge tube generates glow discharge, which causes the gas to emit a laser with a wavelength of 10.64um. After the energy is amplified, after galvanometer scanning and F-Theta mirror focusing, under the control of the computer and laser marking control card, the image, text, numbers and lines can be marked on the workpiece according to the user's requirements.

CO2 laser marking machine consists of: CO2 laser marking machine mainly consists of CO2 laser, 10.64 field lens, 10.64 beam expander, CO2 laser power supply, scanning galvanometer, control computer, laser control card, laser control software, laser machine frame, Laser circulating water system, circuit control system and other components.

CO2 laser marking machine main features: the use of carbon dioxide laser, is a general-purpose model, post-focusing mode, small size, high degree of integration. The machine is suitable for marking large non-metallic materials, such as CO2 laser marking machine paper packaging, plastic products, label paper, leather fabrics, glass ceramics, resin plastics, bamboo products, PCB boards, etc. The CO2 laser is a gas laser with a wavelength of 10.64 um in the far infrared light band. The CO2 gas is charged into the discharge tube as a medium for generating laser light. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, and the gas molecules can be released. The laser is amplified, and the laser energy is amplified to form a laser beam for processing the material.
