Abstract: A system may perform an uptapering process to cause a signal fiber to have a fiber core with a first uptapered thickness profile and a fiber cladding with a second uptapered thickness profile. The system may perform, after performing the uptapering process, an uptapering removal process to cause the fiber cladding of the signal fiber to not have the second uptapered thickness profile. The system may perform, after performing the uptapering removal process, a bundling process to bundle the signal fiber and a set of one or more pump fibers in a bundle configuration. The system may perform, after performing the bundling process, a bundle unification process to cause the bundle configuration to form a unified bundle configuration. The system may perform, after performing the bundle unification process, an attachment process to cause an end of the unified bundle configuration to attach to an end of an output fiber.

Abstract: An optical fiber includes a core configured to transmit laser light and a cladding that surrounds the core. In some implementations, an outer surface region of the cladding is tapered or comprises a plurality of notches. The outer surface region of the cladding is configured to cause an aiming beam that falls incident upon the outer surface region of the cladding at a first incidence angle to fall incident upon an outer surface region of the core at a second incidence angle to allow the aiming beam to couple into the core.

Abstract: In some implementations, a waveguide may comprise an inner core to receive a first beam and an outer core surrounding the inner core to receive a second beam that is displaced from the first beam by an offset. The outer core may comprise a beam guiding region that rotationally expands over a length of the waveguide into an annulus that concentrically surrounds the inner core or a partial annulus that partially surrounds the inner core. For example, the beam guiding region may be defined by one or more low refractive index features that have a varied orientation and/or a varied shape over the length of the waveguide such that the second beam enters the waveguide as an offset beam and exits from the waveguide as a ring-shaped beam or a partial ring-shaped beam.

Abstract: In some implementations, a fiber optic combiner may comprise an enclosing tube having a geometric shape and multiple optical fibers bundled within the enclosing tube. In some implementations, the multiple fibers comprise at least one optical fiber having a core and a non-circular cladding surrounding the core. The non-circular cladding may cause the multiple optical fibers to have a larger tube fill factor and a lower expected beam parameter product increase factor relative to the multiple optical fibers all having circular claddings.

Abstract: In some implementations, a high-brightness combiner comprises a fiber bundle that comprises a plurality of optical fibers associated with a packing geometry that defines a shape of an outer periphery of the fiber bundle. The high-brightness combiner further comprises a capillary structure, comprising a glass enclosure surrounding the fiber bundle, wherein the capillary structure includes an outer periphery, and an inner periphery with a shape that corresponds to the shape of the outer periphery of the fiber bundle.

Abstract: An optical pump-signal combiner includes a first end and a second end. The optical pump-signal combiner is tapered down from the first end to the second end. At a first cross-section of the optical pump-signal combiner associated with the first end, the optical pump-signal combiner includes a capillary, a plurality of signal fibers that are disposed within the capillary, and a plurality of pump fibers that surround the capillary. Each signal fiber, of the plurality of signal fibers, includes a signal core and a signal cladding, and each pump fiber, of the plurality of pump fibers, includes a pump core and a pump cladding. At a second cross-section of the optical pump-signal combiner associated with the second end, the optical pump-signal combiner includes a unified fiber that includes an outer combined-cladding, a combined-pump core, an inner combined-cladding, and a combined-signal core.

Abstract: In some implementations, a cladding light stripper includes an optical fiber that includes a core and an exterior cladding, and a light removal component. The exterior cladding of the optical fiber circumferentially surrounds the core of the optical fiber. The exterior cladding includes a first portion, a second portion, and an intermediate portion disposed between the first portion and the second portion. The intermediate portion is bidirectionally tapered. The light removal component is disposed on one or more regions of a central section of the intermediate portion.

Abstract: In some implementations, an optical system comprises a laser engine that comprises multiple laser sources configured to generate multiple lasers associated with different wavelengths and a signal combiner configured to combine the multiple lasers associated with the different wavelengths into broadband laser light. In some implementations, the optical system may further comprise a process cable configured to transmit the broadband laser light and a process head configured to receive the broadband laser light via the process cable such that the process head may focus the broadband laser light onto a workpiece.
