Carbon dioxide laser cutting machine, also called CO2 laser cutting machine, this kind of laser cutting machine currently has great advantages in cutting non-metallic materials, and is widely used. Let me briefly introduce the principle, configuration and application range of carbon dioxide laser cutting machine Check out this machine.

The reason why the carbon dioxide laser cutting machine is called carbon dioxide laser cutting machine is because it is a laser cutting machine using carbon dioxide laser, which is a gas molecule laser. The working gas is carbon dioxide gas, and the auxiliary gas is nitrogen, xenon, etc. The wavelength of the laser light is 10.6 microns. Good stability, energy conversion efficiency up to 25%, high output laser power. The principle of laser generation: CO2, N2, He and other mixed gases are filled in the CO2 laser discharge tube, and the ratio and total pressure can be changed within a certain range (generally: CO2: N2: He=1:0). There are three different forms of movement in any molecule, one is the movement of electrons in the molecule, which determines the energy state of the electrons, and the second is the vibration of the atoms in the molecule, the atoms are constantly doing periodic vibrations in their equilibrium positions, which determines the vibration of the molecule Energy level, the third is the rotation of the molecule, to determine the rotational energy state of the molecule, you can go to this part of Baidu to understand the relevant knowledge. CO2 lasers use the conversion between the vibrational energy level and the rotational energy level of CO2 molecules to generate laser light.

What is a CO2 laser cutting machine

Carbon dioxide laser cutting machine we refer to carbon dioxide laser tube here, in fact, CO2 laser and radio frequency (rf) tube, commonly used in laser marking machine, marking machine glass tube is also very useful, but compared with radio frequency tube marking machine , laser marking, the glass tube laser under continuous working conditions for a long period of time is unstable, the service life is short, and the efficiency is lower than that of the radio frequency tube. However, in terms of cutting, glass tube lasers are basically used, because the requirements for cutting depth are generally relatively high, so it is more economical to use glass tube lasers with high power and low cost. The CO2 laser cutting machine is cooled by water, and the cooling water circulates in the glass tube. In the working state, the glass tube laser will generate high voltage, so never touch the laser when the laser cutting machine is running.
