Medical Laser Mixture
Medical Laser Gas Mixtures are produced for carbon dioxide lasers. These lasers are not only more precise and less intrusive, they also provide an efficient method of performing surgeries that are highly sterile or have expectations of significant blood loss. The CO2 laser produce intensive infrared radiation, this can be focused to vaporize tissue smaller than a millimeter. This is done by exciting the molecules in the Medical Laser Gas Mixture, a combination of carbon dioxide, helium, and nitrogen, in a discharge tube which then converts the electrical energy into optical energy.
Few examples are given below
CO2 4.5-9% + N2 13.5-15% + Helium Balance
CO2 1-10% + CO 1-10% + N2 1-10% + Helium Balance
