Abstract: A machining process, associated with a workpiece, may include controlling, by a control device, a pulse repetition frequency (PRF) of an ultrashort pulse laser. The PRF may be controlled to maintain a substantially constant distance, on the workpiece, between adjacent pulses on a path. The substantially constant distance may be maintained despite changes in a speed of the path relative to the workpiece. An amount of energy of each pulse on the path may be substantially constant despite changes to the PRF associated with controlling the PRF.

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 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.
