How Do CO2 Laser Cutters Work?
A CO2 laser machine operates by utilizing carbon dioxide gas as the primary medium to generate a laser beam. The basic principle behind its operation involves exciting the gas molecules through electrical energy, which then emits a high-powered laser beam. The laser is directed onto the surface of the material to be cut or engraved. The material absorbs the laser energy, causing it to heat up, melt, or vaporize, resulting in precise cuts or markings.
The key components that make up a CO2 laser cutter machine include the laser tube, power supply, control panel, cooling system, and the optics that focus the laser beam onto the material. Some machines also come with an automated CNC (Computer Numerical Control) system to ensure precision and high-quality cuts.
CO2 laser machines can be used for different types of cutting and engraving depending on the material. The laser beam can be focused to create narrow, high-energy beams that cut through materials like wood, plastic, acrylic, metal, and even fabric with ease.
