New Development Of Crystalline IR Fibers

Crystalline fibers are considered as the most promising fibers for the region 5÷20 μm. The relation of optical and mechanical characteristics of fibers with parameters of the initial crystals and their extrusion is shown. The mechanisms of optical losses including those induced by ∝ - or UV-radiation are discussed together with the optical damage of fibers, induced by continuous or pulsed radiation of CO2-laser.
