METHOD FOR LASER MATERIAL MACHINING AND LASER-MACHINING INSTALLATION

A method for laser material processing includes generating a first pulsed laser beam that forms a first focus zone, and processing the material with the first pulsed laser beam in order to produce first modifications. The first modifications form a shielding surface. The method further includes gene...

Beschreibung
Zusammenfassung:	A method for laser material processing includes generating a first pulsed laser beam that forms a first focus zone, and processing the material with the first pulsed laser beam in order to produce first modifications. The first modifications form a shielding surface. The method further includes generating a second pulsed laser beam that forms a second focus zone, which is formed in elongated fashion along a second focus zone axis and is formed by constructive interference of laser radiation that passes at an angle toward the second focus zone axis. The method further includes processing the material with the second pulsed laser beam to produce second modifications in a second section of the material. At least one part of the laser radiation passes at the angle toward the second focus zone axis impinges on the shielding surface.
