METHOD FOR LASER FUSION USING ABLATION COATING

摘要

FIELD: physics, optics.SUBSTANCE: invention relates to laser material processing, particularly a method for laser fusion using an ablation coating. The method involves determining the surface region of a fusible substance where fusion is to be carried out and depositing a layer of ablation material thereon; laser irradiation of said ablation layer until fusion of the substance and complete removal of said ablation layer; the laser radiation power, irradiation mode and thickness of the ablation layer are selected depending on the radiation absorption coefficient of the fusible substance during transition thereof to a liquid phase; further depositing new portions of ablation material on the irradiated area during irradiation with removal of the irradiated ablation material until the onset of fusion of said substance.EFFECT: fusing a material with laser radiation with an arbitrary wavelength independent of whether said wavelength belongs to the absorption region of the fused material.3 cl, 3 dwg, 1 ex
