    • Collisional absorption effects are ignored because for the particular examples considered, propagation lengths are speckle lengths and for plasma densities and temperatures of interest, these effects are a correction.

    • note
    • If Landau damping dominates collisional damping, then Langmuir wave momentum is transferred to superthermal electrons which will take a significantly longer time to equilibrate with the ions. In such a regime there will be a nonlocal relationship between momentum injection due to the fundamental SRS process, and the transfer of this momentum to the ions.
