[0002] CO2 laser tube is a common gas laser device. It uses carbon dioxide gas as the working medium to generate laser. CO2 laser tube is usually used in industrial processing, medical equipment, scientific research and other fields. The working principle of CO2 laser tube is to generate laser by filling the tube with mixed gas and then generating laser through electron excitation. When the current passes through the excitation electrode, the gas molecules are excited to a high energy state and then release laser photons when de-excited.
