VERFAHREN ZUM BEARBEITEN EINES MATERIALES MITTELS LASERSTRAHLBEHANDLUNG

摘要

A method of processing material with a laser beam. The material has two surfaces. The beam is focused by a multilens objective in a number of focal points which are approximately positioned on a common axis with an angle to the first surface. The focal points are spaced apart and used for cutting plates with several focal points being utilized for melting and cutting the plate material. As a result, a good cutting notch is obtained with good separation of the cut parts and poor adhesion of slag.
