Notes:
The angular and spectral distribution of (3/2)ω0 light emitted from a CO2-laser-irradiated underdense plasma has been measured. The results are interpreted with the help of Thomson scattering measurements of two-plasmon decay plasma wave k spectra and theoretical predictions based on the process in which pump photons are scattered off two-plasmon decay plasmons. If pump, (3/2)ω0-photon, and decay plasmon satisfy their wave vector matching condition, then the spectra provide good temperature diagnostics. Spectra of light scattered off plasmons having propagated up or down the density gradient are severely broadened.
