DEVICE FOR PROCESSING MATERIALS BY LASER BEAM

摘要

A laser beam machining system that can machine a complicated or curved surface of an object in an accurate and prompt manner, can control the machining depth of the object by controlling the output of laser beams, and can observe the shape of a machined object by using an auxiliary light when machining the object with laser beams is provided. A laser beam machining system comprises: a laser beam generating part(30) oscillating laser beams; and a micromirror device(40) having a plurality of micromirrors which are configured in such a manner that the micromirrors optionally transmit some of the irradiated laser beams(L) to the surface of an object(A) to machine the object into a desired shape after the laser beams oscillated in the laser beam generating part are irradiated onto the micromirrors, wherein the micromirrors can optionally convert light paths of the laser beams oscillated in the laser beam generating part, and the micromirror device controls an output of laser beams(L1) irradiated onto the machining surface area by allowing the light paths to be converted with respect to only some micromirrors among micromirrors corresponding to a machining surface area of the object to be machined.
