Laser marking laser beam is used in a variety of different material surface type permanent marker. Marking effect is achieved by the surface layer material evaporation reveals in-depth material, or through the light causes the surface layer material chemical and physical changes and the" moment " the trace, or through the light burned part of the material, showing the required etching patterns, text.At present, accepted principle is two:" Heat treatment" has a higher energy density of the laser beam ( it is the concentration of energy flow), irradiation in the material being processed on the surface, surface absorption of laser energy, in the illuminated area to produce thermal excitation process, so that the material surface ( or coating ) temperature rise, produce abnormal, melting, evaporation, ablation phenomenon." Cold" with high load energy ( UV ) photon, can break materials ( especially organic material ) or the surrounding medium of the chemical bond, to make the material of non thermal process. This cold processing in laser marking processing is of special significance, because it is not a thermal ablation, but does not produce the " thermal injury" side effects, break chemical bonds of the cold dissection, thus the processing surface layer and nearby area does not produce heat or thermal deformation effects. For example, the electronics industry in the use of excimer laser in the basal material deposited on the chemical substance film, on a semiconductor substrate through the narrow slot.
