Abstract
A laser based processing machine incorporates in the path of a laser beam (7) at least one optical element (1) which has a surface (5) situated in the path of the laser beam (7) and a scavenging medium delivery device which flushes its surface in an essentially counterflow-free fashion. The device includes a delivery element with flow nozzles about a portion of the periphery of the optional element and through which the scavenging medium flows onto the surface of the element and thereacross.
