5-11 μm Supercontinuum Generation Using Cascaded Nonlinearities in Fluoride Fiber and ZGP

We present a femtosecond-pumped, octave-spanning, FTIR-compatible supercontinu-um covering 5-11 μm. The SC is generated with record efficiency in ZGP through intra-pulse DFG of a spectrally broaden fiber laser with a 15-fs pulse centered around 2-μm.
