摘要：
A technologically simple optical fiber cross-section structure with a negative-curvature hollow-core has been proposed for the delivery of the CO2 laser radiation. The structure was optimized numerically and then realized using Te20As30Se50 (TAS) chalcogenide glass. Guidance of the 10.6 mu m CO2-laser radiation through this TAS-glass hollow-core fiber has been demonstrated. The loss at lambda=10.6 mu m was amounted similar to 11 dB/m. A resonance behavior of the fiber bend loss as a function of the bend radius has been revealed. (C) 2011 Optical Society of America
