The use of plasma as an amplification medium is currently discussed because it can overcome current solid-state technology limitations in terms of maximum achievable intensity. Via parametric scattering off a plasma oscillation the energy from a long pump pulse can be transferred into a short seed pulse. Brillouin scattering has the potential to become a robust amplification process. In this thesis we present theoretical and numerical (PIC) studies aimed at better understanding the role of each plasma parameter on the amplification mechanism: the interaction length, the shape of the density profile, the duration of the long pump signal, the relative delay between the seed and pump signals, the chirp of the long pump laser pulse. For the fi...
