The disclosure relates to a beam-forming unit for forming a laser beam and focusing the laser beam onto a workpiece. The unit includes a movable component, an immovable component, and a cooling system configured for movement of a cooling medium to actively cool the movable component. The cooling system has-a cooling water circuit on the immovable component configured for water cooling of both the immovable component and the cooling medium.

An integrated sealing device of a laser machining head for sealing between a hollow cage member and a conduit of the laser machining head is described. The hollow cage member includes a first contact surface and a first opening therethrough. The first contact surface includes a substantially planar portion and an elastically deformable sealing lip extending therefrom. The conduit includes a second contact surface and a second opening therethrough. The sealing lip of the first contact surface is configured to contact the second contact surface to form a seal between the hollow cage member and the conduit.
