We report on infrared supercontinuum (SC) generation through subsequent nonlinear propagation in concatenated step-index fluoride and AsSe fiber. These fibers were pumped by an all-fiber laser source based on an erbium amplifier followed by a thulium power amplifier. ZBLAN and InF fibers were compared for the concatenated scheme. The broadest SC produced was achieved by optimizing the length of the InF fiber. This arrangement allowed the generation of 200 mW infrared SC with high spectral flatness and spanning from 1.4 μm to 6.4 μm.
