Carbon Dioxide Laser
The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers to be developed. The CO2 laser produces a beam of infrared light with the principal wavelength bands centering on 9.4 and 10.6 micrometers (μm).
The carbon dioxide (CO2) laser is lasers based on a gas mixture as the gain medium. Typically, the gas mixture consists of carbon dioxide, Helium, Nitrogen, Hydrogen, Xenon gases and water vapour. It can be operated with DC current, AC current or in radio frequency domain (RF). It exhibits laser action at infrared frequencies, mainly at wavelength of 10.6 micrometer. Average power of CO2 lasers are range from 10 W to many kW and the efficiency range from 10 % to 30 %. The main advantages of CO2 lasers are low cost, high efficiency and long lifetime. There are various methods of generation of laser output from CO2 laser, which are sealed-tube, fast axial flow and Transverse excited atmosphere (TEA).
CO2 lasers utilized in various fields such as industrial, medical and military. Applications of CO2 lasers are metal processing, engraving, skin resurfacing and LIDAR.
