Abstract:
A laser-radiation delivery system comprising:a diode-laser having an output-facet from which the laser-radiation is emitted;an optical-fiber for delivering the laser-radiation, said optical-fiber having a polished surface on an input-end thereof, said polished surface inclined at an angle to a longitudinal axis of the optical-fiber;said input-end of the optical-fiber being arranged proximate said output-facet of said diode-laser such that radiation emitted from said output-facet is transmitted laterally into said optical-fiber and is incident internally on said polished surface for reflection therefrom generally longitudinally along said optical-fiber;said polished-surface having a reflective coating thereon, said reflective coating arranged to transmit a fraction of the laser-radiation incident on said polished surface, out of said optical-fiber at said input end thereof; anda radiation-detector responsive to the laser-radiation, said radiation-detector located in a position to receive at least a portion of said transmitted fraction of laser-radiation and generating a signal in response thereto.
