Carbon Dioxide Laser (C02 Laser) - How Does it work?
The word Laser is expand as: Light Amplification by Stimulated Emission of Radiation.They work by bouncing and amplifying light between lenses and mirrors to produce an intense beam of light, which is coherent and monochromatic. The material(s) within the laser that are stimulated determines the wavelength of the light produced.
The CO 2 laser was one of the earliest lasers to be developed and is still one of the most useful. CO2 laser i.e. Carbon Dioxide Laser, has been used by medical professionals. The CO2 laser system can be used in several ways: "focused" for cutting skin without bleeding; "defocused" for superficially vaporizing skin; and "ultra pulsed" for facial resurfacing. This technique removes fine lines and wrinkles of the face, smoothes acne scars, and rejuvenates aging and sun-damaged skin as it contours the skin surface.
Carbon dioxide (CO2) lasers work by sending out a concentrated beam of light that affects the skin. Carbon dioxide lasers are the highest power continuous wave lasers that are currently available. The output power to pump power ratio of this laser is up to 20%. This means that if you put in 1W of pump power you could produce 0.2W of laser power. The CO2 laser has high efficiency. The CO 2 laser produces a beam of infrared light with the principal wavelength bands centering around 9.4 and 10.6 micrometers .
The active laser medium of CO2 laser, is a gas discharge which is air cooled. The filling gas within the discharge tube consists primarily of:

How does the Carbon Dioxide Laser work?
The CO2 lasers delivers short bursts of extremely high-energy laser light. This technology actually vaporizes the undesired skin tissue one layer at a time, revealing fresh skin underneath. Often referred to as a pulsed CO2 laser, the laser's highly focused beam enables the dermatologic surgeon to gently remove the skin's surface with a lower risk of scarring and other complications in properly selected patients. Healing generally occurs over a two-month period.
With the help of CO2 laser, we can treat the following types of cancer. These includes:-
