The laser uses a gas mix that contains the following components: carbon dioxide, nitrogen, and helium. When excited with electricity, the nitrogen colliding with the CO2 generates energy in the form of light, which is further amplified. The resulting light is infrared and, once focused, forms a powerful laser beam. With its focus and intensity, the laser can either vaporize or change the texture of a material to make high-contrast, lasting marks on its surface.
