fiber laser with a highereneray density of the laser beam (it is a concentratecenergy flow). irradiating on the surface of the material being processed. Thematerial surface absorbs aser eneray and generates Therma excitation process inthe irradiation area so that the material surface (or coating laver) temperature rises
