Abstract
A method for marking components (2) by a plurality of pulses (4) of a pulsed beam of a laser is disclosed. At first, a melted burr is formed when the marking (2) is being created. Subsequently, the melted burr is removed, whereby the pulsed laser beam is moved over the melted burr at a second speed. The sequential pulses (4) hardly overlap or not at all.

A method for marking components by a plurality of pulses of a pulsed beam of a laser directed at a surface of the component, the method comprising the following steps:
- forming a melted burr at side edges of the marking when the marking is being created whereby, during the creation of the marking, the pulsed laser beam is moved relative to the component at a first speed, so that the pulses overlap;
- and
- removing the melted burr, the pulsed laser beam being moved over the melted burr at a second speed so that the sequential pulses do not overlap or overlap insubstantially.
