  4. Abstract:
  5. A warm relativistic ideal fluid theory is proposed to study the dynamics of laser-induced high amplitude longitudinal waves in rarefied plasmas. It is demonstrated that fluid equations may be closed using an adiabatic approximation in the local rest frame of the plasma fluid. It is shown that considering three-dimensional thermal fluctuations of plasma for an interacting laser pulse that is invariant in transverse directions, considerably changes the features of describing fluid equations compared to that of previously considered one-dimensional thermal-fluctuations models. For a given shape of laser pulse these equations are solved numerically and their results are compared with those obtained from cold fluid theories. © 2009 American Institute of Physics
