摘要：

Experiments examining nonlinear scattering mechanisms of high intensity (2 X 10(18) W/cm(2)) laser light in underdense plasmas were performed. Redshifted second harmonic emission at 45 degrees from the directly backscatterd direction was observed from field ionized plasmas having electron densities ranging up to 10(19) cm(-3). This result is consistent with the doubling of stimulated Raman scattered light from large plasma electron density gradients produced by ponderomotive cavitation.
