摘要：
Fiber optic methods and systems angularly and spatially offset back reflections away from numerical apertures of a core and inner cladding of a double-clad fiber (DCF) that transmits light to downstream opticai interfaces. Back reflections from near and/or far downstream optical interfaces are offset away from the numerical aperture of the core and inner cladding by (1) adjusting an axial length between the DCF end face and the near and /or far reflective optical interfaces, and (2) angling the near and/or the far optical interfaces to angularly and spatially displace back reflections away from the core and inner ciaddmg. No-core fiber fusion spliced to the DCF, or a wedge prism attached to the DCF by index matched gel may be used to adjust the axial lengths and angled the reflections.
