Method and device for laser material processing of a workpiece

摘要

Cutting a workpiece with a laser beam includes using the laser beam to melt and/or vaporize at least a portion of the workpiece, and moving at least one of the workpiece and the laser beam relative to one another to form a cutting front on the workpiece, in which the laser beam includes either at least two different radially polarized beam portions offset relative to each along an advancing direction of the laser beam, or multiple laser beam strips extending along the advancing direction of the laser beam. Each laser beam strip has a different linear polarization direction, and the advancing direction corresponds to a direction along which the workpiece is cut by the laser beam.

1. A method for cutting a workpiece with a laser beam, the method comprising:
using the laser beam to melt, vaporize, or both melt and vaporize at least a portion of the workpiece; moving at least one of the workpiece and the laser beam relative to one another in an advancing direction to form a cutting front on the workpiece, wherein the laser beam comprises a plurality of parallel laser beam strips extending along the advancing direction, wherein each laser beam strip has a different linear polarization direction, and wherein the advancing direction corresponds to a direction along which the workpiece is cut by the laser beam.
