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, 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.

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: A graded index fiber having a refractive index profile that causes a beam to be re-imaged in the graded index fiber with a regular period may include a set of bends that have a bend period matched to or nearly matched to a pitch of the graded index fiber. For example, the set of bends may be formed in the graded index fiber using one or more bending devices that include one or more protrusions that have a periodicity matched to or nearly matched to a pitch of the graded index fiber. A first section of the one or more bending devices may be actuated to move towards a second section of the one or more bending devices such that the one or more protrusions cause the bends to be formed in the graded index fiber.

IPC: H01S3/094

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.
