What is the principle of CO2 laser cutting machine

The principle of CO2 laser cutting machine is to use the transition between the vibration and rotational energy levels of carbon dioxide molecules to generate laser light.

The discharge tube of the carbon oxide laser is filled with mixed gas such as carbon oxide, and its proportion and total gas pressure can be changed within a certain range.

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.

The second is the atomic vibration in the molecule, that is, the atom constantly vibrates periodically around its equilibrium position, and this motion determines the vibrational energy of the molecule.

The third is the rotation of the molecule, which determines the rotational energy state of the molecule.

The CO2 laser cutting machine uses the transition between the vibration and rotational energy levels of carbon dioxide molecules to generate laser light.
