Abstract

This thesis presents a theoretical analysis of the laser pulse driving an electron-hole semiconductor plasma. The plasma wave after being driven by the laser field appears with a lot of physical changes. These changes are in the frequency, amplitude of its wave. Furthermore, its stability also changes from the rest.
In chapter I, entitled ”Introduction”, introduces a lot of the basics about plasma and the basics of the laser-plasma interaction.
In chapter II, entitled ”Electrostatic wave propagation and self-streaming effect in an electron-hole plasma”, introduces the non-linear waves in the electron-hole semiconductor plasma. Using the quantum hydrodynamic fluid system consisting of the continuity, the momentum, and closed by the Poisson equations, investigated for electrons-holes plasma. The effect of the degenerate pressure, Bohm potential, and collision rate are also studied. This system is reduced to a modified non-linear Schrödinger equation. Furthermore, the in/stability regions for the wave are studied, as well as different wave solutions are presented.
