Abstract
The first measurements of the growth and saturation of ion acoustic waves generated by optical mixing are presented. At lower power levels, the parameter dependence of the ion waves is shown to agree in detail with the predictions of optical mixing theory. However, at higher power levels a nonlinear saturation is observed and identified as increased Landau damping due to ion heating.Keywords
