Stimulated Raman scattering of XeF* laser radiation in H<inf>2</inf>

Abstract

Stimulated Raman scattering (SRS) experiments have been performed using an ∼2 J, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\sim0.4 \mu</tex> s pulsewidth XeF* laser as the pump and high-pressure molecular hydrogen as the Raman-active medium. The SRS conversion efficiency and spectral distribution have been characterized as functions of H <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> pressure and pump laser focal parameters. Energy conversion efficiencies of >60 percent have been obtained, with the converted energy in first and second Stokes radiation, at 414 nm and 500 nm, respectively.
