Big Power Co2 Laser Cutting Machine 300W Wood Laser Cutting Engraving Machine.
The discharge tube of the CO2 laser is filled with mixed gases such as CO2, N2, He, etc., the ratio and the total pressure can be changed within a certain range (generally: CO2:N2:He=1:0.5:2.5 The total pressure is 1066.58pa) .Any molecule has three different forms of motion, one is the movement of electrons in the molecule, which determines the energy state of the electrons, and the other is the vibration of atoms in the molecule, that is, the atoms constantly vibrate periodically around their equilibrium positions. It determines the vibrational energy of the molecule, and the third is the rotation of the molecule, which determines the rotational energy state of the molecule. The CO2 laser uses the transition between the vibrational and rotational energy levels of the CO2 molecule to generate laser light.
