Abstract
In this chapter, we go back to laser–plasma interaction by addressing the coupling of the laser waves with the electron plasma waves. So we derive the so-called Raman instability model. In the case of the fixed-ion assumption, it leads to a three-wave coupling system that shows the same structure as the system of Brillouin instability. In the second part of this chapter, we deal with the modelling of the interaction of an ultra-intense laser pulse and a plasma. This leads to the so-called Euler–Maxwell system. We give some mathematical properties of this system and we show how an envelope description may be useful in some cases.
