Two concentric fiber diameters in one laser light cable: The 2in1 fiber makes it possible to weld and cut by means of simple optical exchange

Different applications for laser material processing, such as cutting and welding, require a modification in the laser beam's quality to produce the best results. Therefore, when switching applications, it is usually necessary to change the laser light cable. The new 2in1 fiber that TRUMPF has developed for the Trulaser cell 7040 fiber contains two concentric fiber core diameters in just one laser light cable. During the cutting process, the laser beam is guided into the inner fiber core and during welding into the outer ring core. The 2in1 fiber causes the laser light to reach the work‐piece with just the right depth of sharpness and the correct beam diameter.
