Carbon Dioxide laser Tube

co2 laser tube diagramThe carbon dioxide laser commonly referred to as CO2 laser originally invented back in 1964 by Kumar Patel. At the very core a CO2 laser is basically a gas discharge pointing to a reflector. Usually the gas is contained within an air tight glass tube with a transparent mirror on one end and a totally reflective mirror on the other…the ends are referred to as cathode and anode. The mixed gasses are typically helium, nitrogen, CO2, and hydrogen.

Currently CO2 lasers offer the most powerful and efficient option in terms of a continuous wave laser beam. The gases along with the electricity causes the Nitrogen atoms become excited and powerful that it produces energy so powerful that it exits the tube. The laser beam that is discharged from the excited nitrogen atoms is in the infrared or invisible part of the spectrum with a wavelength from about 800 nm to 1 mm .
