Abstract
The invention relates to a methodand an apparatusfor cutting or ablating a particular material of the workpiece with a pulsed laser beam coupled into a fluid jet. The method comprises producing the pulsed laser beam with at least one laser source, providing the pressurized fluid jet onto the workpiece, and coupling the pulsed laser beam into the fluid jet towards the workpiece. The pulsed laser beam comprises at least two superimposed pulsations selected based on the particular material of the workpiece. A first pulsation has a different power and frequency than a second pulsation.
