Mid- and Far-Infrared Supercontinuum Generation in Bulk Tellurium Spanning from 5.3 $\mu$m to 32 $\mu$m

Daniel Matteo, Sergei Tochitsky, Chan Joshi

Supercontinuum generation is performed in the bulk semiconductor tellurium (Te) with a high-power picosecond CO${}_2$ laser at peak intensities up to 20 GW/cm${}^2$. The spectrum spans…
