Abstract: A fiber connector system provides a pigtailed monolithic terminal block of a fiber connector configured to alter a space distribution of laser output radiation. The output facet of the pigtailed monolithic terminal block is configured to alter the divergence of an output beam allowing collimation, focusing, or any desired distribution without additional optical circuitry. The fiber connector system is operative to couple two fibers from respective different fiber devices and allows positioning additional optical components there between.

Abstract: The present disclosure is a system for the protection of a fiber within a laser system. The system has a water-cooled housing supporting a termination block, which is operative to shield a protective layer of a delivery fiber from back-reflected beams of light. The termination block is manufactured from quartz and is frustconical in configuration and fuseable to the delivery fiber. The delivery fiber has a polymeric protective layer with an acceptance end and a delivery end, and passes through a washer contained within the housing; the washer has a dielectric reflective coating. The system has at least one terminal block connector which further comprises a cone termination block, a reflector, and a set of light guards. The cone termination block is spliced to an output end of the delivery fiber and produces an angle ? so as to reduce propagation of back-reflected light. The reflector is positioned so as to block additional back-reflected light from the protective layer of the delivery fiber.
