Narrow-linewidth and high-efficiency conversion of stimulated Raman scattering (SRS) in a lead vapor heat pipe was observed using a narrow-linewidth and injection-locked XeCl excimer laser system as the pump source. The XeCl laser was continuously tuned over its entire B-X gain curve, from the (0-0) transition to the (0-3) transition, giving it a range of 0.8 nm (307.65-308.45 nm). The laser linewidth was narrowed down to 0.002 A (0.02 cm/sup -1/). The output energy was 310 mJ/pulse, with a repetition rate up to 50 pps and good beam quality. A lead vapor heat pipe operating at 1225/sup 0/C was used as a single-pass stimulated Raman converter, shifting the radiation from 308 to 459 nm. Photon conversion efficiency as high as 80 percent was achieved, using a pump linewidth of 0.01 A.
