Furthermore, the energy density spectrum for electromagnetic wave, Langmuirwave and ion acoustic wave are obtained and used to interpret spectra evolution with time.

The simulated results can be used to explain the laser plasmas filamentation, the langmuir wave's excitation and collapse, and the energy equilibration over both langmuirwave and transverse wave.
