Time-resolved observations of stimulated Raman scattering from laser-produced plasmas

Abstract

Temporally and spectrally resolved measurements of stimulated Raman scattering from high-intensity, 0.532 μm laser–plasma experiments on disk targets are reported. The observed scattering is principally from densities below quarter-critical, and is observed to occur nearly simultaneously over a wide range of wavelengths (0.72 μm<λ<0.9 μm), in short (<50 psec) bursts. Several possible explanations of these data are briefly discussed.
