The invention relates to a laser assembly () comprising a diode laser bar (), a heat sink () and at least one cover (). The laser bar is located between the heat sink and the cover. The heat sink and/or the cover is/are coated with nanowires () or nanotubes via which the contact between the laser bar and the heat sink and/or the cover is established.

Diode laser

The invention relates to the production of an optical or optoelectronic assembly () comprising an active component () and a cooler (). The cooler () is produced by means of a 3D printing method on a composite plate ().

Optical and optoelectronic assembly and method for the production thereof

The invention relates to a transparent auxiliary ring for the adjustment, for the long-term stable operation and for protection of fiber-coupled laser arrangements.

Laser arrangement with auxiliary ring

The invention is directed to a tool head for machining of materials by laser, substantially comprising focusing optics which are arranged in a housing and through which a laser beam bundle is directed to the workpiece surface to be machined, a nozzle which coaxially surrounds the optical axis of the laser beam bundle and conducts gas in the beam direction in order to prevent contamination of the focusing optics by particles released on the workpiece surface to be machined, a pipe which coaxially surrounds the nozzle and which likewise conducts gas for preventing contamination of the nozzle, and a suction device with suction nozzles.
