【摘要】 本文叙述了红外光学纤维对材料的基本要求。介绍了氧化物、硫族化合物、卤化物红外光学纤维材料的研究情况。讨论了卤化物材料的优越性。在卤化物材料中,由于ZrF₄和AlF₃系玻璃有较好的物理化学性质,以及极低的固有损耗值,它们被认为是最有希望的红外光学纤维材料,并且已拉制成了几米长的试验纤维。更多还原

【Abstract】 The basic requirements for infrared transmitting fiber materials are described.A survey is made of researches in infrared optical fiber materials, i.e. oxides,chalcogenides and halides. Advantages of halide materials are discussed, among whichthe ZrF₄ and AlF₃ glass systems are thought to be the most promising ones, because oftheir better physical and chemical properties and the extremely low intrinsic lossvalue. These glasses have been drawn into trial fibers of a few meters length.更多还原
