CO2 laser marking machine is a type of laser marking machine, it works with CO2 laser, so it is called CO2 (carbon dioxide) laser marking machine. The laser is the core factor of a laser marking machine, and it is also the controlling factor of the price of a laser marking machine. What is the working principle of CO2 laser marking machine? To understand the working principle of CO2 laser marking machine, you must first understand the CO2 laser. CO2 laser is a kind of gas laser, it can produce the wavelength of 1064nm, and the laser power of CO2 laser is very large, and it has high electro-optical conversion efficiency. The CO2 laser can be said to be the laser with the largest laser power at present. The CO2 laser uses CO2 gas as a working medium to make CO2 interact with other auxiliary gases to generate laser light for processing.
At present, CO2 laser marking machines on the market are mainly divided into two types: one is a CO2 laser marking machine that uses a glass tube as a CO2 laser, and one is a CO2 laser marking machine that uses a radio frequency tube as a CO2 laser. The CO2 laser marking machine is mainly applied to non-metallic materials, but the CO2 laser marking machine using RF tubes as lasers can be applied to corresponding metal materials.
The CO2 laser is a gas laser with a wavelength of 1064um in the infrared light frequency band. It uses carbon dioxide gas to fill 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, which can release gas molecules. The laser, after amplifying the laser energy, forms a laser beam for processing the material. The computer-controlled galvanometer changes the laser beam optical path to achieve automatic marking.
