Abstract: An aberration corrector and a method to reducing a spherical aberration are disclosed. The aberration corrector has a radial, rotationally symmetric variation of refractive index including a term varying in proportion to a fourth degree of a distance from the optical axis. Since the spherical aberration causes a wavefront deviation proportional to the fourth degree of distance from the optical axis, the spherical aberration can be reduced by the aberration corrector when its thickness causes the exact amount of the phase delay corresponding to the wavefront deviation, but with an opposite sign.

Abstract: A laser beam delivery system includes an optical beam launcher device and a waveguide assembly. The optical beam launcher device includes an optical relay system that includes a beam splitting optic that is configured to cause a laser beam that is input into the optical beam launcher device to be split into a first laser sub-beam and a second laser sub-beam, cause the first laser sub-beam to transmit to a first region of an input lens of the waveguide assembly, and cause the second laser sub-beam to transmit to a second region of the input lens. The waveguide assembly is configured to transmit the first laser sub-beam and the second laser sub-beam from the input lens to an output lens of the waveguide assembly, wherein the first laser sub-beam and the second laser sub-beam transmit from the waveguide assembly and form an output laser beam.

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: A pulse stretching fiber oscillator (or laser cavity) may comprise a chirped fiber Bragg grating (CFBG) and an optical circulator arranged such that a first portion of a beam that is transmitted through the CFBG continues to propagate through the laser cavity while a second portion of the beam that is reflected from the CFBG is stretched and chirped by the CFBG and directed out of the laser cavity by the optical circulator. Accordingly, a configuration of the CFBG and the optical circulator in the laser cavity may enable pulse stretching contemporaneous with outcoupling, which may prevent deleterious nonlinear phase from accumulating prior to stretching.

Abstract: An in-fiber beam scanning system may comprise an input fiber to provide a beam, a feeding fiber comprising an imaging bundle with multiple cores embedded in a first cladding that is surrounded by a second cladding, and an in-fiber beam shifter that comprises a first multibend beam shifter coupled to the input fiber, a graded index fiber following the first multibend beam shifter, and a second multibend beam shifter following the graded index fiber and coupling into the feeding fiber. In some implementations, the first multibend beam shifter is actuated by a first amount and the second multibend beam shifter is actuated by a second amount to shift the beam in two dimensions and deliver the beam into one or more target cores in the imaging bundle.

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 assembly provides dispersion control, modelocking, spectral filtering, and/or the like in a laser cavity. For example, the optical assembly may comprise a diffraction grating pair arranged to temporally and spatially disperse a beam on a forward pass through the optical assembly, a reflective device at an end of the optical assembly, and a focusing optic arranged to create a beam waist at the reflective device. The beam waist created at the reflective device may cause the beam to be inverted on a reverse pass through the optical assembly, and a temporal dispersion and a spatial dispersion of the beam may be doubled on the reverse pass through the optical assembly to form a temporally and spatially dispersed output from the optical assembly.

Abstract: An optical fiber device may include a core including a primary section and a secondary section. The secondary section may include at least one insert element inserted within the primary section at an off-center location with respect to a center of the primary section. The secondary section may twist about an axis of the optical fiber device along a length of the optical fiber device. A rate of twist at which the secondary section twists about the axis may increase from a first end of the optical fiber device toward a second end of the optical fiber device. The secondary section being twisted about the axis may cause an optical beam, launched at the first end of the optical fiber device, to be at least partially converted to a rotary optical beam at the second end of the optical fiber device.
