Carbon Dioxide Laser: Important Features and Applications.
Kumar Patel of Bell Labs invented the CO 2 laser in 1964. In this article, I discuss only some features of CO 2 laser. Carbon dioxide laser is another gas laser with a high power of about 60 kW. Carbon dioxide laser is still one of the most used types of laser. Carbon dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%. The CO2 laser produces a beam of infrared light with the principal wavelength bands centering on 9.6 and 10.6 micrometers (μm). [5] I will tell you about infrared light later in this article. A test target bursts into flame upon irradiation by a continuous-wave kilowatt-level carbon dioxide laser. Lasing medium: It uses CO2 and N 2 in equal ratios, with traces of He and water vapor as the lasing medium. CO 2 is the laser-active material, and lasing transition happens between specific vibrational levels of CO 2 molecules. The sp
