Abstract
Conversion efficiencies for stimulated Raman scattering (SRS) in Pb vapor are strongly influenced by the buffer gas pressure and species used in the Pb vapor heat pipe. As the Raman gain is proportional to the Pb density and to the transient response time T2, changes in performance can be caused by variations in either of these parameters. To resolve this issue, the authors report a new form of delayed probe experiment to monitor the effects of variations in T2 independent of changes in the Pb density. They observed the pressure dependence of T2 for the Pb system in He, Ar, and Xe buffer gas species over the temperature range 1120-1300°C. The buffer gas pressure/species dependence of Pb density has also been observed using ground state optical absorption. The authors have developed a model of the Pb vapor SRS system that explains the parametric behavior of SRS conversion efficiency in terms of T2 changes.
