Time-resolved spectra of backward and forward stimulated Raman scattering were measured from the interaction of 0.26 {mu}m laser radiation with foil targets. The plastic foil targets were designed to go underdense before the peak of the 450 psec, 2{times}10{sup 15} W/cm{sup 2} laser pulse. The Raman spectra were quite narrow at any one time ({Delta}{omega}/{omega}{similar to}0.05) and shifted to shorter wavelengths during the pulse. The backward Raman spectra can be well predicted by assuming that the Raman occurs in a disk-shaped region on the top of the parabolic density profile, using well accepted threshold estimates.
