A CO2 laser is a gas laser with that A mixture of carbon dioxide, nitrogen and helium serves as an active medium. The carbon dioxide molecules are stimulated. If an infrared photo meets a carbon dioxide molecule, a new photon is created.

CO2 lasers are the most commonly used laser cutting machines. These co2 gas mixture which is charged using a high-intensity electronic current. The CO2 laser is highly efficient and accurate, with a wavelength of around 10.6 micrometer’s it is most useful for laser cutting non-metallic materials such as wood or plastics.
