Abstract:
Thomson-scattering signals can be significantly modified by convective gains associated with the stimulated Raman scattering and stimulated Brillouin scattering instabilities as the scattered light traverses the probe beam. Gain results in amplification and narrowing of the redshifted (i.e., Stokes) scattered light, whereas blueshifted (anti-Stokes) features are depleted and broadened, making the relative prominence of these features a key signature of gain. Neglecting to account for instability growth has been a ubiquitous source of error in previous Thomson-scattering measurements.
