Abstract
A laser marking system for marking a product comprising a laser source for providing a laser beam, a marking head for projecting the laser beam on to the product, a housing comprising an extraction device configured to generate a flow of extraction fluid for extracting matter generated by an interaction between the laser beam and the product, and a controller for controlling the laser source and the marking head. The laser marking system further comprises an umbilical assembly connecting the housing to the marking head.
