Optically pumped high-pressure mixtures of NH3 in N2 are shown to be efficient broadband amplifiers of pulsed CO2 radiation. In a dilute NH3 mixture at 6 atm a single-pass gain of 150 (21.8 dB) was measured for the 10P(34) CO2 transition. Gain was observed in NH3 at pressures as high as 10 atm. Experimental measurements were made for a range of wavelengths in the 10.7 μm region, and the results compared with calculations based on a rate-equation model
