Stimulated Raman scattering (SRS) of the 308-nm output of XeCl lasers in Pb vapor was studied, using short-duration pump pulses (5 ns). Substantially reduced conversion efficiency resulted compared with use of long pulses. In addition, previously unreported transient effects became apparent and were studied. A technique is described for improving short-pulse conversion. Using this technique efficiencies comparable to long-pulse systems were obtained. A parallel experiment using electrical dissociation of PbCl2 to produce free Pb provides a lower-temperature alternative to the heat pipe oven.
