Abstract: An optical fiber may include a core in which core-guided light generated by one or more light sources propagates along a length of the at least one optical fiber, one or more claddings, surrounding the core, to guide cladding-guided light generated by the one or more light sources along the length of the at least one optical fiber, and a reflector structure machined into the at least one optical fiber. The reflector structure may include multiple angled facets arranged at one or more respective angles relative to an axis of the optical fiber to reflect at least a portion of the core-guided light and/or the cladding-guided light passing through the optical fiber.

Abstract: An optical device may include a fiber to provide a beam. The optical device may include a graded-index element to expand or magnify the beam. An input facet of the graded-index element may be adhered to an output facet of the fiber. The optical device may include an optical transformation element to transform the beam after the beam is expanded or magnified by the graded-index element. An input facet of the optical transformation element may be adhered to an output facet of the graded-index element.

Abstract: A cladding stripper includes a plurality of transversal notches or grooves in the outer surface of an exposed inner cladding of a double clad optical fiber. Position and orientation of the notches can be selected to even out cladding light release along the cladding light stripper, enabling more even temperature distributions due to released cladding light. The notches on the optical fiber can be made with a laser ablation system.

Abstract: A cascaded harmonic generator, for cascaded optical harmonic generation from an optical beam provided by a laser source, may include a second harmonic generator to generate a second harmonic optical beam based on a residual beam associated with the optical beam. The cascaded harmonic generator may include a third harmonic generator to generate a third harmonic optical beam based on the second harmonic optical beam and the optical beam. The third harmonic generator may be positioned in an optical path upstream from the second harmonic generator. A harmonic generator delay time, associated with the optical path, may be approximately equal to, or may be an approximate integer multiple of, a laser source round-trip time.

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: In some implementations, an optical system includes a multicore input fiber comprising multiple cores that are each configured to support an independent singlemode laser; a delivery fiber comprising a single core configured to support multiple modes; and a signal combiner, coupled to the multicore input fiber and coupled to the delivery fiber. In some implementations, the signal combiner is configured to receive multiple independent singlemode laser inputs from the multicore input fiber and to combine the multiple independent singlemode laser inputs into a multimode output that is provided to the delivery fiber.

Abstract: An optical assembly may comprise an input fiber to provide a beam, a process fiber comprising a ring-shaped outer core surrounded by a cladding, and a first beam shifter arranged to receive the beam from the input fiber and to shift the beam spatially to illuminate the ring-shaped outer core of the process fiber. The optical assembly may further comprise a second beam shifter arranged to receive the beam from the first beam shifter and to add skew to the beam that is launched into the ring-shaped outer core of the process fiber.

Abstract: In some implementations, an optical fiber may include a core and a cladding surrounding the core. The core and the cladding may provide light guidance along the optical fiber in a light propagation direction. The core may have a taper in the light propagation direction in a section of the optical fiber. A diameter of the core may decrease independently of a diameter of the cladding in the section of the optical fiber.
