An aircraft de-icing system is disclosed in which a laser beam generator is positioned on an aircraft, a beam of radiant energy is generated and directed toward the critical surfaces of the aircraft to create a footprint upon the surface of the aircraft, and the beam is manipulated so that the footprint is moved about the aircraft surface for removing ice, snow or water from the critical aircraft surfaces. One or more laser beam generators are preferably disposed remotely from the area to be de-iced, and the beams are preferably reflected from one or more mirrors so that the mirrors may be adjusted to enable the beams to illuminate the critical surfaces of the aircraft. The laser beams preferably have a wavelength that is preferentially reflected by the aircraft surface and absorbed by ice, snow and water, so that the beam heats and removes ice, snow and water from the aircraft surface as the beam's footprint is moved thereabouts.
