10 {\mu}m 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 {\mu}m. The optimal pump wavelength and partial pressure of CO2 for generating 10 {\mu}m pulses are found

Lasing is studied in CO2 pumped at ~4.3 µm by a tunable Fe:ZnSe laser. Gain is measured at ~10 µm at pressures ≤12 atm where gain bandwidth is broad enough for potential picosecond pulse amplification.
