Paper Abstract

The nonlinear propagation of two high-intensity laser pluses of circular polarization in thin foil targets is investigated theoretically and by simulation. The two laser pulses illuminate a foil normally from both sides and create a spatially confined relativistic election plasma. The solutions depend on the phase relation of the two laser pulses. High order harmonics are found when frequencies and/or polarizations of the two pulses differ. The harmonics compound to a train of sub-femto-second pulse in the time domain. Under certain conditions, an instability occurs and can destroy the foil. Energetic electrons are produced due to the instability.
