Direct observation of stimulated-Brillouin-scattering detuning by a velocity gradient.
Phys Rev Lett 90:15 (2003) 155003
Abstract:
We report the first direct evidence of detuning of stimulated Brillouin scattering (SBS) by a velocity gradient, which was achieved by directly measuring the frequency shift of the SBS-driven acoustic wave relative to the local resonant acoustic frequency. We show that in the expanding part of the plasma, ion-acoustic waves are driven off resonance which leads to the saturation of the SBS instability. These measurements are well reproduced by fluid simulations that include the measured flow.Experimental study of proton emission from 60-fs, 200-mJ high-repetition-rate tabletop-laser pulses interacting with solid targets

Abstract:
Proton emission from 60-fs, 200-mJ high-repetition-rate tabletop-laser pulses interacting with solid targets was studied. A maximum proton energy of 1.5 MeV was measured for Mylar targets of thickness 20-40 μm. Results showed a maximum energy of 950 keV for 12μm for aluminum targets, and 850 keV for 12.5μm for copper targets.Finite temperature dense matter studies on next-generation light sources
