Overview of laser types and their wavelengths

The term laser is the abbreviation for the English term Light Amplification by Stimulated Emission of Radiation. (A highly focused light that has a specific wavelength of high energy depending on the laser medium) The medium can be, for example, gas such as argon, carbon dioxide (CO2) or a crystal such as ruby, or an electrical medium such as diodes. Depending on the application, a corresponding laser with a selected wavelength is used, which applies the laser beam to the diseased tissue with the help of different medical laser probes.
