| Abstract: | The production of a broadband supercontinuum spanning from 1.8 μm to >7.5 μm is reported which was created by pumping a chalcogenide glass waveguide with ≈320 fs pulses at 4 μm. The total power was ≈20 mW and the source brightness was  100 that of current synchrotrons. This source promises to be an excellent laboratory tool for infrared microspectroscopy. |
