    摘要： An optical fiber combiner comprises a double-clad fiber (DCF) and one or more multimode fibers (MMFs). DCF comprises a transition portion, a DCF taper portion, and an output section coupling to the DCF taper portion, whereas each of-_MMFs comprises an MMF taper configured to be fused around-_DCF in the transition portion. MMFs are configured to carry a combined optical energy (COE) and to couple to DCF. COE passes through the MMF taper with larger divergence of higher-order modes generated and coupled into-_DCF, whereas the DCF taper portion can partially offset the larger divergence. COE coupled, when traced through the output section, emerges in the air with a smaller output beam divergence of the higher-order modes, thereby preserving some of the higher-order modes in the output section and increasing a coupling efficiency of COE coupled from-_MMFs to-_DCF with improved thermal performance.

    摘要： A method of forming a coupler, the method comprising: (a) heating a portion of an optical fiber having multiple cores and an initial diameter; and (b) applying a tensile force across the portion such that the portion stretches, thereby reducing the initial diameter to a reduced diameter sufficient to cause optical signals propagating in one or more of the multiple cores to leave their respective cores and enter other cores of the fiber.

    摘要： A system for combining multiple fiber amplifiers, or multiple fiber amplifiers. The system includes a fiber combiner with multiple cores for connecting with the multiple fiber amplifiers and for combining the beams of the fiber amplifiers into a single beam. The fiber amplifiers are aligned, tapered, and stretched.A method for combining fiber amplifiers includes emitting a beam from a tapered fiber combiner and transmitting and coupling a portion of the emitted beam back into the fiber combiner via a feedback fiber. The transmission and coupling of the feedback fiber includes mixing the feedback fiber with the output of an auxiliary laser and boosting the feedback fiber by a pre-amplifier. The feedback fiber is split into a plurality of beams by a fiber splitter. The beams are fed into an array of fiber amplifiers and combined with output of the individual fiber amplifiers to form the tapered fiber combiner.

    摘要： A high power fiber laser system has a combiner configured of a plurality of single mode (SM) fibers which are fused together so as to define an output end of the fiber combiner. The fused SM fibers radiate respective fiber outputs, which collectively define a multimode (MM) combiner output. The SM fibers each are configured with such an optimally small numerical apertures (NA) that the MM combiner output is characterized by a minimally possible beam quality factor (M2) for the plurality of SM fibers. To reduce the possibility of burning of the components of the fiber laser system with a multi-kilowatt combiner output, a coreless termination block is fused to the output end of the fiber combiner and configured so as to provide expansion of the combiner output without modifying the minimally possible M2 factor thereof.
