Disclosed is an optical system for laser machining that enables simpler and more reliable machining of several patterns simultaneously on the same part. The system comprises an ultra-short pulse laser source for generating a source laser beam; a device with a separation means for separating a source laser beam into a plurality of separated laser beams, such that each of the separated laser beams is directed in a direction of propagation specific thereto; a spatial offsetting unit for obtaining, from the plurality of separated laser beams, a plurality of offset laser beams such that each offset laser beam can propagate around a main axis of propagation A specific thereto and is capable of describing a movement around the main axis of propagation A; and a focusing means configured to focus each offset laser beam on a workpiece in the direction of the axis of propagation specific thereto.
An optical system for laser machining, comprising:
A method for providing a plurality of offset laser beams with respect to a plurality of separated laser beams for machining a part and comprising the implementation of the following steps:
