Abstract

Infrared optical fibers operating at 2-12 μm have been required for IR sensing applications such as the radiometric thermometer and CO₂ laser power applications, e.g., laser surgery. Various halide crystals and chalcogenide glasses have been proposed.^1,2 In these materials, chalcogenide glasses have the advantage that they exhibit no increase in scattering loss due to the plastic deformation which usually occurs in the crystalline fibers.
