Spatial Profiles of Stimulated Brillouin Scattering Ion Waves in a Laser-Produced Plasma

Abstract: The ion fluctuation axial profile is measured by Thomson scattering in an inhomogeneous laserproduced plasma. The electron temperature and plasma drift velocity at the location of the measured ion waves and the plasma density profile are simultaneously measured. The measured ion fluctuation profile is compared to the profile predicted by convective growth of the stimulated Brillouin scattering instability calculated from the measured hydrodynamic profiles. PACS numbers: 52.35.Fp, 52.35.Mw, 52.40.Nk, 52.50.Jm S… Show more

“…Subsequently, the utility of TS was also demonstrated in laser-produced plasmas to measure electron temperatures and the characteristics of ion acoustic and electron plasma waves in a large number of studies using open-geometry disk and exploding foil plasmas (e.g., Refs. [33][34][35][36][37][38][39][40]. In experiments at the Nova laser facility we have verified the theoretical TS cross section calculations6*27~28…”

“…This process, which has a potential to reduce the efficiency of the laser fusion implosion through scattering of the incident laser energy away from the target, has long been a research subject of extensive theoretical 1-6 and experimental studies. [7][8][9][10][11][12][13] However, there remain significant anomalies between the observed SBS signal levels and those calculated from theoretical models of the convective SBS gain from thermal noise in laser plasmas. This necessitates more theoretical efforts in the modeling of the SBS with regard to its source and location in the plasma.…”
