Abstract
Stimulated Raman scattering has been investigated in H2 and in different H2 - foreing gas mixtures with a UV - preionized XeCl discharge laser (308 nm) as the pump. Helium, neon and nitrogen have been tested as foreing gases.The energy conversion efficiency of the pump laser beam to Stokes beams has been investigated as a function of the foreing gas concentration and of the pump beam energy. In all the investigated mixtures with 50 percent of H2, the energy conversion efficiency to the first Stokes was more than 70% higher than that obtained in pure H2 at the same total pressure (40 bar) and pump energy (60 mJ).
