Stochastic Electron Acceleration in Laser-plasma Interactions available in PDF, EPUB and Kindle. The generation of energetic electron beams in the interaction of an intense laser pulse with plasma is of great interest for many different applications and different mechanisms of electron acceleration have been proposed and studied analytically, numerically, and experimentally over many years. However, due to the multidimensional spatio-temporal characteristics of the electromagnetic (EM) fields and strong nonlinearity of relativistic electron dynamics, the analytic investigations of the mechanism of electron acceleration in the earlier studies are quite limited and thus more profound analysis is needed. This dissertation work is devoted to the analytic investigation of the electron dynamics in the fields of lasers and quasi-static EM fields by employing a novel Hamiltonian, which, by finding proper canonical variables, is time-independent when an appropriately selected perturbation is absent. Such characteristics of the new Hamiltonian can significantly simplify the analysis of electron dynamics. Three different configurations of laser waves and quasi-static EM fields will be considered: counter-propagating laser waves, laser radiation with quasi-static EM fields that can confine the electron motions (e.g., EM fields in the ion channels), and single laser wave but with spatially periodic quasi-static EM fields (e.g., EM fields in electric and magnetic undulators), where the Hamiltonian, canonical variables and choice of perturbations are different for these cases. The mechanism of the electron acceleration will be examined, paying attention to the stochastic acceleration, where the physics underlying the stochastic electron motion is revealed and the maximum electron energies in all cases are obtained.

This book was released on 2002. Electron Acceleration Mechanisms in the Interaction of Ultrashort Lasers with Underdense Plasmas available in PDF, EPUB and Kindle. An experiment investigating the production of relativistic electrons from the interaction of ultrashort multi-terawatt laser pulses with an underdense plasma is presented. Electrons were accelerated to tens of MeV and the maximum electron energy increased as the plasma density decreased. Simulations have been performed in order to model the experiment. They show a good agreement with the trends observed in the experiment and the spectra of accelerated electrons could be reproduced successfully. The simulations have been used to study the relative contribution of the different acceleration mechanisms: plasma wave acceleration, direct laser acceleration and stochastic heating. The results show that in low density case (1 percent of the critical density) acceleration by laser is dominant mechanism. The simulations at high density also suggest that direct laser acceleration is more efficient that stochastic heating.

A Superintense Laser-Plasma Interaction Theory Primer available in PDF, EPUB and Kindle. The continuous trend towards higher and higher laser intensities has opened the way to new physical regimes and advanced applications of laser-plasma interactions, thus stimulating novel connections with ultrafast optics, astrophysics, particle physics, and biomedical applications. This book is primarily oriented towards students and young researchers who need to acquire rapidly a basic knowledge of this active and rapidly changing research field. To this aim, the presentation is focused on a selection of basic models and inspiring examples, and includes topics which emerged recently such as ion acceleration, "relativistic engineering" and radiation friction. The contents are presented in a self-contained way assuming only a basic knowledge of classical electrodynamics, mechanics and relativistic dynamics at the undergraduate (Bachelor) level, without requiring any previous knowledge of plasma physics. Hence, the book may serve in several ways: as a compact textbook for lecture courses, as a short and accessible introduction for the newcomer, as a quick reference for the experienced researcher, and also as an introduction to some nonlinear mathematical methods through examples of their application to laser-plasma modeling.
