Beschreibung
Zusammenfassung:	A laser material processing head, such as a remote welding head, has an output with a protective optic configured to pass an emitted laser to a working area. The protective optic, such as a cover slide of the output, protects other optics inside the head and is a replaceable, spare part. To prevent at least some debris expelled from the working area from reaching the protective optic, a nozzle is mounted to the head adjacent to the protective optic. The nozzle has an inlet and an outlet for the gas. The outlet has a curvilinear profile configured to fan a cross-jet of the gas in the plane between the protective optic and the working area. The profile of the nozzle reduces the amount of gas needed to divert the debris from the protective optic.
