Abstract
A sealed integrating reflective enclosure contains a laser diode, coupling optic, and input ends of transport fibers. A detector is positioned to capture stray scattered radiation emanating from the laser diode emitters and rear facets, coupling optic and transport fiber input ends. The detector is positioned such that stray radiation undergoes at least one reflection within the enclosure before being detected by the detector. The detector can be positioned inside the integrating enclosure, or outside the integrating enclosure opposite a detection hole that is sealed by a translucent diffuser or window. The reflected integrated light detected by the detector is an accurate indication of the optical output generated by the laser diode and coupled into the transport fibers.
