Multi-octave coherent mid-infrared supercontinuum generation out to 11μm via intra-pulse difference frequency generation in ZGP
On demand | Presented live 22 April 2024 
Abstract
We present a multi-octave, mid-infrared supercontinuum source spanning from 3.6μm and extending into long-wave infrared region out to 11μm with an exceptionally high conversion efficiency of 8.2% and output power of 39 mW. These results were enabled by intra-pulse difference frequency generation involving a femtosecond Thulium doped fiber laser, an indium fluoride fiber and a zinc germanium phosphide crystal.
