Abstract
The effects of H2, He, and N2 buffer gases on the efficiency of the cw 12.08 μm NH3 Raman laser are studied experimentally. The laser output power is increased by nearly 60% with the addition of H2 or He, which we essentially attribute to the high thermal conductivity of these buffer gases. In the optimum conditions (NH3/H2:1/1 mixture with 0.35 Torr partial pressure of NH3) 3.3 W output power at 12.08 μm is obtained which corresponds to 11% power conversion efficiency.
