An update on laser treatment
The term ‘laser’ is an acronym for ‘light amplification by stimulated emission of radiation’. Laser light is coherent and can therefore be focused to a very small spot size maintaining a very high irradiance. Lasers are named by the lasing medium that is stimulated to produce light, which in turn determines the characteristics of the light emitted. The light is delivered as a continuous, pulsed or pseudocontinuous beam.
