The thermal energy of the laser light beam allows simultaneous cutting, coagulation of vessels, and sterilization. The beam is produced by inducing a "population inversion" of excited atoms in a lasing medium. This stimulated emission of light is then amplified to create the lasing effect. Each type of laser causes a different tissue response consistent with its wavelength, energy fluence, and tissue absorption properties.
