Abstract: An optical element may include a plurality of subsurface induced scattering centers formed in the optical element, where the plurality of subsurface induced scattering centers scatter light passing through the optical element. In some implementations, the plurality of subsurface induced scattering centers may form a scattering region in the optical element. Additionally, or alternatively, the plurality of subsurface induced scattering centers may spatially vary transmission of light through the optical element. The optical element may be an optical waveguide, a bulk optic, and/or the like.

Abstract: An optical fiber endcap device may include an input facet spliced onto an input fiber and an output end through which counterpropagating light enters the optical fiber endcap device. The optical fiber endcap device further includes a plurality of angled facets that are arranged at respective angles relative to an axis of the optical fiber endcap device to reflect at least a portion of the counterpropagating light back through the output end of the optical fiber endcap device.

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.

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.
