    Abstract: PURPOSE:To obtain a polycrystalline optical fiber for IR light which is straight and is free from defects such as bending and waving by extruding the optical fiber for IR light perpendicularly downward while exerting tension thereto in the same direction. CONSTITUTION:A weight 7 is mounted to the end of the optical fiber 6 for IR light right after the fiber is extruded and exposed from a die 1. Then the tension equivalent to the weight 7 is perpendicularly downward exerted to the extruded fiber 6. The extruded fiber 6 is made entirely free from bending by making preliminarily the extruding hole direction of the die 1 to coincide with the perpendicular direction. The weight 7 is particularly effective for correcting the bend when the plasticity of the fiber 6 right after the extrusion is large. The trouble in the case of protecting the polycrystalline optical fiber with a pipe, etc. is thus eliminated if such fiber is used as an optical waveguide to be used for a laser surgical knife, laser beam processing machine, etc. using laser light of high-density energy.

    Abstract: PURPOSE:To obtain an optical fiber which is particularly suitable for IR rays and of which the refractive index changes gradually from the core to the clad by depositing and diffusing the mixed crystal material of a metallic halide compd. or the metallic halide mixed crystal material of the compsn. different from the above-mentioned mixed crystal by evaporation on the surface of the mixed crystal material of the fiber- shaped metallic halide. CONSTITUTION:A branch pipe 14 for contg. the metallic halide 16 is provided in the central part of a straight pipe part 12 made of a thick-walled transparent quartz tube and the part 12 and 14 are arranged to be heated respectively by heaters 18, 19, by which the straight pipe part of the device is constituted. The fiber 24 made of the mixed crystal material of the metallic halide such as TlBr-TlI or AgCl-AgBr is supported between a pair of supports 20 and 22 and is supported into such straight pipe part. The inside of the pipes 12, 14 is evacuated to a vacuum and is then heated and TlBr different from the mixed crystal material 24 or AgCl-AgBr different from the mixed crystal 24 in the compsn. ratio is deposited by evaporation as the metallic halide 16, by which the optical fiber having the refractive index changing continuously from the core to the clad part is obtd. The loss in the fiber side face is thus decreased, the divergence of the light at the end face is decreased and the condensability is improved.
