Abstract

The invention relates to a method for cutting parts (4) to be machined, using a pulsed laser (6) that outputs a beam (12) of laser pulses. The method is characterised in that a given cut is carried out using a single laser pulse, essentially for forming an opening (14) in the machined part. To this end, the method comprises a quick relative movement between the part and the laser beam (12) with a pulse duration that is sufficiently long, depending on the relative movement, so that the laser beam can run at least on the predetermined length for a given cut. Each laser pulse preferably has an initial power peak for piercing the machined part when the cutting operation is carried out in an inner region of the part.
