The interaction of intense laser pulses (power>30 TW) with underdense plasmas has been studied. In the regime where the pulse length is much longer than the plasma period (τl≫2πωp−1), the laser pulse is found to be self-modulated at the plasma frequency by the forward Raman scattering instability. Wavebreaking of the resulting plasma wave results in energetic electrons being accelerated to more than 100 MeV. Reducing the pulse length so that τl∼2πωp−1, but retaining the same power, also leads…

TLDR
A nonlinear 1D theory is developed which describes some important aspects of intense laser-plasma interactions and finds coherent harmonic generation using a linearly polarized laser to be most efficient for short laser pulses and can be enhanced by the presence of large amplitude plasma wakefields.
