The invention relates to a mass-optimized mirror for laser processing and a method for cooling the mass-optimized mirror in laser processing. DOLLAR A It is preferably used in laser processing, especially for beam-shaping laser mirrors for two- and three-dimensional laser surface processing of semi-finished or finished products made of any material and combination of materials, for example as a scanner mirror, application (e.g. removal, drilling, cutting, welding, hardening, coating, etc.) . DOLLAR A According to the invention, in the case of the mass-optimized mirror, the thickness of the mirror is reduced to the absolutely necessary minimum and the self-cooling of the mirror, which is no longer guaranteed thereby, is compensated for by at least one additional cooling device coupled to the mirror. DOLLAR A In the method for cooling the mass-optimized mirrors, it is provided according to the invention that the mass-optimized mirror is cooled during the laser processing process in such a way that an expanding gas is blown through a nozzle precisely onto the location of the mirror surface (reaction surface) on which the laser beam hits directly without affecting the laser beam itself. |
