Abstract
The linear instability analysis of stimulated Brillouin backscatter (SBS) is revisited to study the effect of nonlocal electron heat transport that enhances the density modulation over that caused by the ponderomotive pressure. It is found that the intensity threshold is lowered by a factor of roughly the inverse of 1+1000 (ne/nc)ln Λ(Z3/2/TeV2)/λμ, where TeV is the electron temperature in eV and λμ is the laser wavelength in microns, provided that λμTeV2(nc/ne)≫50 ln Λ√Z. A similar reduction in the threshold for Langmuir decay is found, which, in the case of stimulated Raman scattering (SRS), may lead to a reduced saturation level for SRS.
