Stimulated Compton backscatter of incident Nd:glass laser photons (h&slash;&ohgr;≃ 1 eV) from free electrons (n<1019/cm3at &kgr;T≃ 103eV) in laser−induced fusion plasmas is investigated. The threshold for stimulated amplification of reflected radiation against spontaneous loss is 109W/cm2incident intensity while the low gain of the system determines the threshold effectively at 1015W/cm2. For 5×1018free electrons/cm2in the plasma, steady state reflectivities of 10−4are calculated for 1016W/cm2incident intensity. This results from the gain being driven to small values when stimulated photon scatter dominates particle collisions and thereby tends to level the resonant scattering interval of the electron momentum distribution. At lower incident intensities or on the time scales of the transients, interesting experiments might be designed to examine this phenomenon.
