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.

Abstract: A high power single mode ("SM") laser system includes an amplifier configured with a monolithic fiber to rod fiber waveguide which is structured with a multimode ("MM") core and at least one cladding surrounding the core. The MM core is configured with a small diameter uniform input region receiving and guiding a SM signal light, a mode-transforming frustoconica! core region expanding outwards from the input region and a relatively large diameter uniform output position. The high power laser system is further structured with a MM pump light delivery fiber having a numerical aperture NA 2 , which is at most equal to that one of the output core portion. The amplifier and pump light output fiber traverse an unconfined deli very cable and terminate upstream from a mirror which is configured to focus the incident pump light into the core of the amplifier in a counter-propagating direction. The mirror is further structured with an opening aligned with the optical axis of the amplifier and configured to provide a lossless passage of amplified signal light in a propagating direction.

Abstract: A fiber connector system provides a pigtailed monolithic terminal block of a fiber connector configured to alter a space distribution of laser output radiation. The output facet of the pigtailed monolithic terminal block is configured to alter the divergence of an output beam allowing collimation, focusing, or any desired distribution without additional optical circuitry, The fiber connector system is operative to couple two fiber's from respective different fiber devices and allows positioning additional optical components there between.

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.
