Available in PDF, EPUB and Kindle. Book excerpt: This dissertation covers several important aspects of relativistically intense laser–microplasma interactions and some potential applications. A Paul-trap based target system was developed to provide fully isolated, well defined and well positioned micro-sphere-targets for experiments with focused peta-watt laser pulses. The laser interaction turned such targets into microplasmas, emitting proton beams with kinetic energies exceeding 10 MeV. The proton beam kinetic energy spectrum and spatial distribution were tuned by variation of the acceleration mechanism, reaching from broadly distributed spectra in relatively cold plasma expansions to spectra with relative energy spread as small as 20% in spherical multi-species Coulomb explosions and in directed acceleration processes. Numerical simulations and analytical calculations support these experimental findings and show how microplasmas may be used to engineer laser-driven proton sources. In a second effort, tungsten micro-needle-targets were used at a peta-watt laser to produce few-keV x-rays and 10-MeV-level proton beams simultaneously, both measured to have only few-μm effective source-size. This source was used to demonstrate single-shot simultaneous radiographic imaging with x-rays and protons of biological and technological samples. Finally, the dissertation discusses future perspectives and directions for laser–microplasma interactions including non-spherical target shapes, as well as thoughts on experimental techniques and advanced quantitative image evaluation for the laser driven radiography.

This book was released on 2009 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of relativistically intense laser radiation with plasma is rich in nonlinear processes like laser pulse self-modulation and self-focusing, wake-field excitation, wave-breaking and the creation of relativistic solitary structures. The creation and evolution of solitary structures during relativistic laser-plasma-interaction is discussed in this book. A relativistic Maxwell-fluid model is formulated to investigate these solitary structures. We discuss the creation of pre-solitons and their transition to post-solitons. The longitudinal and transversal stability of stationary soliton solutions to the Maxwell-fluid model are examined by numerical linear stability analysis. The transversal instability is identified to be the dominant process. Relativistic electrostatic wave-breaking often is part of the nonlinear evolution of unstable relativistic solitons. A process that will eventually lead to wave-breaking for every electrostatic wave in a cold relativistic plasma is presented. The formalism allows a generalization of known criteria to the relativistic regime and to estimate the breaking time.

This book was released on 2016 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nature of how light interacts with plasma is fundamentally altered when the bulk of the electrons become relativistic, manifested as an enhanced transparency of the plasma. Three dimensional particle-in-cell simulations demonstrate that this enhanced transparency of a relativistically hot plasma is sensitive to how the energy is partitioned between different degrees of freedom. For an anisotropic electron distribution, propagation characteristics, like the critical density, will depend on the polarization of the electromagnetic wave. Despite the onset of the Weibel instability in such plasmas, the anisotropy can persist long enough to affect laser propagation. This plasma can then function as a polarizer or a wave plate to dramatically alter the pulse polarization. We further demonstrate using numerical simulations that a high intensity laser pulse propagating through a classically overcritical, relativistically transparent plasma can generate a strong azimuthal magnetic field, leading to copious quantities of synchrotron radiation. An optimal channel setup is proposed and tested to produce a collimated beam of multi-MeV photons.

Book excerpt: Femtochemistry VII presents the most recent developments in femtochemistry and highlights the significance of the field today. This book contains extracts from the proceedings, presentations and posters from the Femtochemistry VII conference, held in Washington D.C., on July 17-22, 2005. The stimulating conference was opened by Professor Ahmed Zewail (1999 Nobel Prize Winner), and as was evident by the attendees at the conference, had a very active program with the presentation of numerous talks and a large number of posters. This collection of papers reflects the remarkable progress that has been made in femtosecond spectroscopy, and especially to its emergence as a field of research devoted to chemistry and biology, giving rise to femtochemistry and femtobiology. Subjects covered include imaging, structural dynamics, and spectroscopies, fundamentals of reaction dynamics, salvation phenomenta, liquids and interfaces, aggregates/particles/surfaces, protein dynamics and photobiology, quantum control, and intense laser-matter interactions. Subjects covered by this book include imaging, structural dynamics, and spectroscopies; fundamentals of reaction dynamics; salvation phenomenta; liquids and interfaces; aggregates/particles/surfaces; protein dynamics and photobiology; quantum control; and intense laser-matter interactions. This book would appeal to chemists, physicists and biologists in the fields of atomic and molecular science. * Contains the most recent developments in Femtochemistry from the Femtochemistry VII conference* Highlights the significance of femtochemistry today* Displays extracts from the proceedings, presentations and posters from the conference
