Abstract

The total-attenuation coefficient αT in polycrystalline thallium bromoiodide fibers varies as λ−2, in sharp contrast to the Rayleigh λ−4 dependence in silica fibers. We developed a model showing that this λ−2 attenuation results from the combination of bulk scattering from large-scale, optically thin imperfections and surface scattering and absorption. The model also explains our scattering sphere result that the attenuation coefficient that is due to scattering, αS, at 10.6 μm increases linearly with fiber length, in contrast to the situation in glass fibers in which αS is constant along the fiber.
