(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.
