SHIELDING AGAINST LASER BEAMS

When a workpiece (1) is perforated by means of a laser beam (2), a shielding (4) is arranged behind the opening (3) that is to be produced by said laser beam. The shielding (4) is arranged in the direction of the beam. The laser beam is destructured on said shielding (4) by means of scattering, refl...

Beschreibung
Zusammenfassung:	When a workpiece (1) is perforated by means of a laser beam (2), a shielding (4) is arranged behind the opening (3) that is to be produced by said laser beam. The shielding (4) is arranged in the direction of the beam. The laser beam is destructured on said shielding (4) by means of scattering, reflections and/or absorption within a greater volume or in a greater optical path length. Workpiece areas (1'') or machine parts are thus protected behind the shielding (4).
