An environment friendly nonlinear chalcogenide glass fiber with a Ge-Sb-Se core and a Ge-Se cladding is fabricated for bright broadband mid-infrared (MIR) supercontinuum (SC) generation. The fabricated Ge-Sb-Se/Ge-Se fiber with a core diameter of 6 mu m shows zero group velocity dispersion at similar to 4.2 mu m and similar to 7.3 mu m. By pumping the fiber with a length of 11 cm at 4.485 mu m with 330 fs pulses, we achieve a SC covering the 2.2-12 lm spectral range and with an output average power of similar to 17 mW. This bright broadband SC source is promising for high-resolution MIR spectroscopy.
