Overview of laser types and their wavelengths

The term laser is the abbreviation for Light Amplification by Stimulated Emission of Radiation. (A highly concentrated light, which depending on the laser medium has a certain wavelength of high energy) 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.
