Temporally and spectrally resolved (90 2 harmonic emission and stimulated Raman scattering has been observed from thin foils irradiated by double pulse 010.53 pn laser light. Asymmetric W O 2 spectrum from the prepulse can he explained by the spectral model including ?U,-plasmon-photon coupling and the effects of plasmon refraction. The Raman signal from the main pulse is broad corresponding ;o densities up to O.?Zn, for the Raman process. An anomalous red shift -1000 . A from the (90 2 frequency observed during the main pulse indicates inverse resonance absorption of the Raman-plasmons. because the red shift is too large to be explained b j the ?to,-insiabilit~.
