Observation of stimulated Compton scattering from resonant electrons in a laser-produced plasma

An experimental study of stimulated Compton scattering (SCS) from resonant electrons in a laser-produced plasma is reported. Up to 1.9 kJ of 350-nm laser light was used to irradiate 3-μm-thick CH targets in 1.3 to 3.3-ns pulses at intensities up to 1.3×${10}^{15}$ W/${\mathrm{cm}}^2$. SCS was detected by making time-resolved measurements of the emission near 420 nm. The measurements are compared to the results of theoretical modeling.
