Abstract: Some embodiments may include an apparatus usable in a laser system. The apparatus may include at least one optical filter to receive a laser beam or laser light along a first axis, the laser beam or laser light generated by the laser system, wherein the at least one optical filter is configured to reflect one of light having a selected wavelength or a remainder of the laser light along a second axis that is non-parallel with the first axis and pass the other of the light having the selected wavelength or the remainder along a third axis that is parallel to the first axis. Other embodiments may be disclosed and/or claimed.

Abstract: Some embodiments may include an optical assembly usable to process light output from a laser source. The apparatus may include a housing to receive a distal end of an optical fiber that outputs the laser light; one or more actively cooled or passively cooled beam traps contained within the housing or coupled to the housing; and one or more optical apertures located inside the housing, at least one of the optical apertures to define a numerical aperture (NA) of a first portion of the laser light based on a radial dimension of the at least one optical aperture, the at least one optical aperture arranged to pass the first portion of the light and redirect a second different portion of the laser light to the one or more actively cooled or passively cooled beam traps. Other embodiments may be disclosed and/or claimed.
