Detection of prompt stimulated Brillouin backscatter is reported from an experiment in which a high-power pulsed CO/sub 2/ laser irradiates an independently produced theta-pinch plasma. Analysis of the backscatter signal indicates that significant SBS gain is limited to a time period near peak incident power. The restriction on SBS gain is attributed to a varying temperature gradient.
