Abstract

Polycrystalline alkali halide fibers were fabricated using a hot extrusion technique. Core/clad fibers of KBr/KC1 had losses as low as 0.1 dB/m at 10.6 μm, but the average loss for 800/1000 μm fiber was 0.69 ± .32 dB/m. The salt fibers were coated with teflon to mini-mize surface fracture from microcleavage cracks and to protect the fiber from contamination. The maximum output power we have obtained from the fiber is 67 watts of cw CO2 laser power. This corresponds to a power density of 13.3 kW/cm2. The 1000 μsalt fiber has been bent into a 12 cm diameter circle with a 5% reduction in transmission.
