Stimulated Raman scattering (SRS) in a CO/sub 2/ laser(lambda/sub 0/ -- 10.6 ..mu..m) produced plasma has been studied experimentally. The enhanced electron plasma wave (epw) fluctuations observed with ruby laser Thomson scattering have been compared with the scattered infrared (IR) spectra and the high-energy (near 100 keV) electrons. No scattered IR light in the range 1.5lambda/sub 0/ <2lambda/sub 0/ was observed although the epw fluctuations suggested there should be IR light in this range. A signal was detected at 2lambda/sub 0/ which is due to the two plasmon decay instability. The number and energy spectra of the fast electrons are well correlated with the Thomson scattered wave vector spectra.
