CsI Crystalline Fiber for Infrared Transmission

Abstract

We report a melt grown cesium iodide crystalline fiber whose transparency extends from the ultraviolet to infrared region. Transmission losses of the fiber inserted in a teflon jacket are measured at the wavelengths of 0.63 and 10.6 µm, and in the spectral range from 0.8 to 1.6 µm, respectively. Overall optical and mechanical properties of the fiber show its availability.
