Cold working (ultraviolet) photons with high load energy can break the chemical bonds inside the material (especially organic materials) or the surrounding medium, causing non-thermal process damage to the material. This kind of cold working is of special significance in laser marking, because it is not thermal ablation, but it does not produce "thermal damage" auxiliary, cold peeling that breaks the chemical bond, so it does not affect the inner layer and the surrounding area of the processed surface layer. Produce heating or thermal deformation.
Because the transients generated by the hot processing light source cause damage to the outer and middle surface of the mask, which affects the filterability of the mask, the Lingxiu Laser replaces the "cold processing" ultraviolet laser to mark the surface layer of the mask.
