Spatial and temporal coexistence of ion-acoustic waves (IAW) and electron-plasma waves (EPW), driven, respectively, by stimulated Brillouin and Raman scattering, at significant levels of amplitude, has been observed under the modified conditions of a laser-plasma interaction. The results were obtained using a secondary interaction beam to modify the growth of the instabilities and the multiplexing technique of a streak camera to simultaneously record the temporal and spatial evolution of Thomson-scattered light from both the IAW and the EPW. {copyright} {ital 1999} {ital The American Physical Society}
