Abstract
A coupling system for coupling a beam of radiant energy from a laser to a fiber optic cable includes a secondary transmission path which surrounds the input end of the fiber optic cable and provides an optical path for energy which is not transmitted by the fiber optic core but is lost. Displaced from an output end of the secondary transmission path is a multi-faceted reflector. The reflector is displaced sufficiently from the output end of the secondary transmission path so that the power density of the radiation incident thereon is reduced sufficiently so as to not damage the facets thereof. The coupling system is contained within a heat sink which receives the reflected and lost radiant energy harmlessly converting same to heat.
