  • Coupling means for monomode fiber
    Patent number: 4805976
    Abstract: The fiber end which is developed as the situs of coupling to incident laser radiation is inserted into a transparent capillary (14) and beveled in order to mask reflections out of the direction of the optical axis. The capillary is roughened on the outside and is surrounded by a light-absorbing layer (15) which acts as a light trap, to eliminate such disturbing stray light as may be coupled into the fiber alongside the core (11).
