Abstract
This Letter presents the first experimental evidence of seeding of ion acoustic waves (IAW) from stimulated Brillouin scattering along the resonant direction between two interaction beams. Using a secondary interaction beam at a reduced intensity acting as seed, a well defined resonance was observed along the bisecting direction between the two laser beams. A strong reduction of the IAW was observed along off-resonance directions, including for backscatter of the primary beam.Keywords
