CO2 Laser Cutters
How Does a CO2 Laser Cutter Work?
A CO2 laser cutter uses gas-based laser technology, mainly carbon dioxide, to create a powerful laser beam. The process kicks off when electricity excites a gas mixture inside a sealed tube. This reaction produces a high-energy light beam that is focused through mirrors onto the material being cut or engraved. The laser wavelength of about 10.6 micrometers is particularly good at cutting non-metal materials because of how well those materials absorb the light.
The actual cutting happens when the focused beam moves across the surface of the material at different speeds and strengths. This allows it to either cut through or engrave designs into various substrates. As the laser interacts with the materials, it generates heat that vaporizes them along a precise path, which is controlled by a computer.
What Materials Can a CO2 Laser Cutter Process?
CO2 laser cutters are well-known for their ability to work with many non-metal materials. Here’s what they can handle:
- Wood: Perfect for detailed cuts and engravings.
