We have generated 50 mJ of 16.9-μm radiation by stimulated rotational Raman scattering in 3 atm of H2 gas pumped by a CO2 TEA-laser source. Threshold was reached by injection of a few microjoules of 16.9-μm radiation generated by four-wave mixing. We achieved 25% peak power, or 40% peak photon conversion efficiency.
