Surface treatment of materials with one or more laser beams involves moistening surface to be treated, and light input surface if transparent material, with absorbing/partially absorbing fluid

摘要

The method involves removing material from the surface (12) of the material (10) with directly or indirectly acting laser radiation (16). The surface to be treated and, in the case of an optically at least predominantly transparent material, another surface of the material through which the laser beam passes into the material is moistened with absorbing or partially absorbing fluid (14).
