Abstract
A low loss cladded halide fiber for transmission of infrared energy is provided, and a process for making the same by growing a single crystal ingot from a powder of a core halide, extruding or machining the ingot to provide a cylindrical billet core, assembling the billet core, preferably wrapped in a polymer film, within a sleeve member of a second halide of lower refractive index than the core, prepared in the same fashion as the core, and coaxially core drilled to accept the billet core. The assembled composite billet is covered with a polymer film, heated, and extruded to form a polymer coated fiber having a diameter in the range of 75 to 2,000 microns. The extruded fiber may be rapidly cooled as it leaves the extrusion die to minimize grain size and scattering loss and may be contained in a coaxial outer strength member.
