摘要
利用熔融淬冷法制取了 (Ge10Te43)90-AgI10和Ge10Sb10Se80玻璃，并采用挤压法制成了一种对环境无害的双材料类芯包结构的悬吊芯光纤.制成的光纤具备3~11 μm的宽谱透光性，其最低损耗仅为0.5 dB/m.讨论了GeTe-AgI悬吊芯光纤的光场模式和红外激光光斑，并利用中红外光参量放大器进行激光泵浦，获得了光谱宽度为1.6~8.9 μm的超连续谱输出.
Abstract
(Ge10Te43)90-AgI10 and Ge10Sb10Se80 glasses were prepared using melt quenching method, and an environmentally friendly suspended-core fiber based on the above two glasses was fabricated via a extrusion technique. The fiber exhibits excellent transmission window ranging from 3 to 11 μm with a minimum loss of 0.5 dB/m, the optical energy and beam spot of the suspended-core fiber were also investigated. In addition, a supercontinuum spanning from 1.6 μm to 8.9 μm was obtained as pumped by a mid-infrared optical parametric amplifier.
