METHOD OF AND SYSTEM FOR LASER MACHINING A PRIMARY SURFACE OF A WORKPIECE USING A MASKING DEVICE MADE OF, FOR EXAMPLE, CORUNDUM

摘要

A laser machining system (10) for machining a workpiece (15) is disclosed. The workpiece (15) may have a primary surface (30) and a secondary surface (40). The system has a laser emitter (20) configured to emit a laser beam (25). The system has a masking device (35) having an absorbing portion (45) formed from corundum. The absorbing portion (45) may have a surface portion (100) shaped to approximately correspond to a contour of an inner side (105) of the primary surface (30) of the workpiece (15).
