Gas Laser A gas laser is a type of laser engraving system that utilizes a gas-filled tube as the laser medium to generate coherent light for engraving purposes. Common types of gas lasers include CO2 lasers, helium-neon (HeNe) lasers, and argon-ion lasers, each operating at specific wavelengths suited for different engraving applications. Gas lasers offer advantages such as high power output, reliability, and versatility, making them popular choices for engraving a wide range of materials, including plastics, metals, and organic substrates. |
