Mid- and Far-Infrared Supercontinuum Generation in Bulk Tellurium Spanning from 5.3 m to 32 m
Daniel Matteo, Sergei Tochitsky, Chan Joshi
Supercontinuum generation is performed in the bulk semiconductor tellurium (Te) with a high-power picosecond CO laser at peak intensities up to 20 GW/cm. The spectrum spans…

Lasing in 15 atm CO2 cell optically pumped by a Fe:ZnSe laser
Dana Tovey, Jeremy Pigeon, Sergei Tochitsky +7
10 μm lasing is studied in a compact CO2-He cell pressurized up to 15 atm when optically pumped by a ~50 mJ Fe:ZnSe laser tunable around 4.3 μm. The optimal pump wavelength and par…
