摘要

The control of laser pulse propagation in bulk nanoplasma gas was demonstrated using a prepulse to modify the transient refractive index. The microscopic absorption and expansion dynamics were also studied with pump-probe Rayleigh scattering and soft X-ray fluorescence. It was found that the optimal delay between the prepulse and the main pulse for maximum Rayleigh scattering was longer than that for maximum X-ray emission. The separation of the peaks of absorption and scattering verified the prediction of one-dimensional self-consistent hydrodynamic nanoplasma model.
