摘要：
The overall properties of the Ga5Sb10Ge25Se60 glass fiber have been compared to the Te(20)AS(30)Se(40)I(10) glass fiber, which has been intensively studied for infrared applications. The first has a significantly higher glass transition temperature and better thermal mechanical properties, leading to stronger fibers. The second glass is transparent further in the infrared region. The infrared transmission cut-off is about 15 mum for the Ga5Sb10Ge25Se60 glass and 18 mum for the Te(20)AS(30)Se(40)I(10) glass. CO2 laser power delivery has been performed with these two fibers. Even with a significantly higher absorption, the Ga5Sb10Ge15Se60 glass fiber can withstand the same power level as the Te20As30Se40I10 glass fiber. (C) 2003 Elsevier B.V. All rights reserved.
