Stimulated Raman backscatter from long--scale-length, magnetically confined underdense plasma has been studied for incident CO/sub 2/ laser intensities up to 2.5 x 10/sup 11/ W/cm/sup 2/. Above an incident threshold of 4 x 10/sup 10/ W/cm/sup 2/ the reflectivity rapidly rises to a saturated value of 0.7%. The measurements are in good agreement with a theoretical model of absolute instability which includes both collisional and Landau damping due to hot-electron production.
