Gas Discharge Laser A gas discharge laser is a type of laser engraving system that utilizes a gas-filled tube as the active medium to generate laser light. Common types of gas discharge lasers include CO2 lasers, helium-neon (HeNe) lasers, and argon-ion lasers. Gas discharge lasers work by exciting the gas molecules within the tube with electrical discharge, causing them to emit coherent light at specific wavelengths. These lasers are widely used in engraving applications due to their versatility, high power output, and ability to engrave a variety of materials with precision and speed. |
