  • Publication number: 20220077648
    Abstract: The disclosed ultra-high power all fiber laser system is configured with multiple spaced apart fiber lasers outputting respective laser beams respective paths, The disclosed system is further configured with a tapered fiber-bundle including at least one central guiding fiber and a plurality of peripheral guiding fibers. The disclosed system further has a multiclad, delivery fiber configured with a double-bottle neck cross-section and provided with at least two concentric and radially spaced apart inner and outer cores. The inner core is coupled to the peripheral guiding fibers while the inner core is spliced to the central guiding fiber so that a system output emitted from the inner core of the delivery fiber has a different beam shape from the system output emitted from the outer core.

  • Patent number: 10906129
    Abstract: The present invention provides a multi-fiber laser output system that delivers at least three fiber outputs arranged in a circumferential pattern or otherwise at least four distinct laser outputs from a single processing cable. The present invention allows for controlling the at least three laser modules and delivering their respective outputs in a pre-determined sequence in a single processing cable, thereby providing multiple processing steps on a work piece that heretofore required separate optics for each beam. The at least three laser outputs are optimized for use in creating spot welds, seam welds or virtual wobble welds when used for seam welding.

  • Patent number: 10759000
    Abstract: The present invention provides a fiber laser system that delivers from a single processing cable a multibeam output. The present invention allows for controlling multiple fiber laser modules and delivering their respective outputs in a pre-determined sequence but in a single processing cable, thereby providing multiple processing steps on a work piece that heretofore required separate optics for each beam. Custom fiber laser systems that combine processing steps tailored for a specific industrial application such as pre-heating, cutting, cleaning, welding, brazing, ablating, annealing, cooling, polishing and the like can be readily provided because of the present invention.
