The CO2 laser marking machine utilizes an infrared light band and a 10.64μm gas laser. By charging CO2 gas into a high-voltage discharge tube, it creates a glow discharge, prompting gas molecules to release laser energy. This energy is amplified into a laser beam that vaporizes the object’s surface for engraving.
The primary distinction from other types lies in the laser source: it uses a gas laser, unlike fiber lasers. Its core components—laser source, scan head, control card, and lens—are crucial for assessing its quality.
