Device for cutting material by means of a laser beam

摘要

Device for cutting material by means of a laser beam, which device (1) comprises a laser source (2) for generating a laser beam (3) with an optical axis (10) and a focussing lens (8) for focussing said beam (3), characterized in that between said laser source (2) and said focussing lens (8) are provided a first and a second retardation plate (4 and 5) and a refraction element in between them, which is provided rotatable and tiltable with respect to said optical axis (10) of the incoming light beam.
