Abstract: An optical component has a bottom part located in an opening defined by a surface, wherein a distance between a sidewall of the bottom part of the optical component and a sidewall of the opening is non-uniform in which a width of a first section of the opening or a first section of the bottom part of the optical component is narrower than a width of a second lower section of the opening or a width of a second lower section of the bottom part of the optical component; and an adhesive is located in the opening between sidewalls.

Abstract: A laser module service shelf is generally presented. In some embodiments, a laser system includes a rack including a stack of slots to support a plurality of laser modules in first positions within the rack, wherein the rack comprises a pair of struts extending at opposite sides of an opening in the rack through which the laser modules may pass, and a module service shelf attachable to the struts to support a weight of one of the laser modules in a second position that is cantilevered from the rack in alignment with the opening and one of the slots, wherein the module service shelf comprises a plurality of detachable sections. Other embodiments are also disclosed and claimed.

Abstract: An apparatus for scattering light may include: an optical fiber having a first length; and a sleeve, having a second length shorter than the first length, around the optical fiber. The optical fiber may include: a core; and cladding around the core. The sleeve may include fiber-optic material. The fiber-optic material may be substantially polymer-free. An outer surface of the sleeve may be roughened to scatter the light out of the sleeve through the roughened surface. A method of forming an apparatus for scattering light may include: providing a sleeve having a first length, the sleeve having inner and outer surfaces; providing an optical fiber having a second length longer than the first length; passing the sleeve around the optical fiber or threading the optical fiber through the sleeve; and roughening at least a portion of the outer surface of the sleeve.

Abstract: Apparatus include a first laser diode situated to emit a beam from an exit facet along an optical axis, the beam as emitted having perpendicular fast and slow axes perpendicular to the optical axis, a first fast axis collimator (FAC) optically coupled to the beam as emitted from the exit facet and configured to direct the beam along a redirected beam axis having a non-zero angle with respect to the optical axis of the first laser diode, a second laser diode situated to emit a beam from an exit facet of the second laser diode along an optical axis parallel to the optical axis of the first laser diode and with a slow axis in a common plane with the slow axis of the first laser diode, and a second fast axis collimator (FAC) optically coupled to the beam as emitted from the exit facet of the second laser diode and configured to direct the beam along a redirected beam axis having a non-zero angle with respect to the optical axis of the second laser diode.
