Abstract:
The excitation of the plasma wake waves by an electron bunch in the presence of an intense electromagnetic radiation with circular polarization has been studied in parametric unstable regimes. In the unperturbed state (in the absence of an electron bunch), the interaction between a pump wave and a plasma is described by the Maxwell’s equations and the nonlinear relativistic hydrodynamic equations for a cold plasma. The excitation of linear waves by an electron bunch is investigated against a cold plasma background. It is shown that, in a certain range of the parameters of the bunch, pump wave, and plasma, the excitation is resonant in character and the amplitude of the excited plasma wake waves increases with distance from the electron bunch.
