Book Description
This report covers research on Nonlinear Heating of Plasmas by High Power Lasers. The overall objective of the program was to study the interaction of intense laser radiation with high density plasma, such as that produced by radiation impinging on a cold target or from a pre-existing plasma.

Book Description
Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.

Book Description
The heating of a dense plasma by a laser through the exciation of parametric instabilities is examined in detail. These instabilities convert laser energy into plasma density fluctuations (or waves) which ultimately result in particle heating by collitionless and collisional wave damping. A comprehensive nonlinear weak-turbulence theory of the saturation of these instabilities is developed, and the saturated plasma wave spectrum for the case of nearly equal electron and ion temperatures is computed. The saturated wave level permits the calculation of the nonlinear absorption coefficient of the laser which can be considerably enhanced over the linear (inverse bremsstrahlung) value for typical laser power densities. The self-consistent propagation of the laser beam, including this nonlinear absorption in an overdense inhomogeneous plasma, is studied in a one-dimensional model; and the reflection coefficient as a function of incident power is computed.

Book Description
This book is an important reference work for the field of high-intensity and high-plasma-density laser-plasma interaction. It summarizes past advances and opens insights into the future. The book covers the essentials from a single particle to dense fluids, and from computational physics to applications for fusion energy or hadron cancer therapy. In addition, it contains clear explanations of the theory of electrodynamics, laser-driven hydrodynamics, Maxwell's stress tensor and Lorentz force, complex refractive index, and relativistic effects in plasmas. Beyond these classical aspects, the book indicates where quantum and classical theory converge. Topics new to this edition include: an introduction to the ponderomotive potential and an overview of related phenomena, including hydrodynamic derivation of nonlinear forces; Richard Feynman and the nonlinearity principle; application of ultrahigh plasma block acceleration for electrons above GeV energy; extremely dense ion blocks for non-thermal picosecond ignition of fusion; and the very first approach to economical power generation using boron fusion with complete exclusion of nuclear radiation problems.

Book Description
The field of high-power laser-plasma interaction has grown in the last few decades, with applications ranging from laser-driven fusion and laser acceleration of charged particles to laser ablation of materials. This comprehensive text covers fundamental concepts including electromagnetics and electrostatic waves, parameter instabilities, laser driven fusion,charged particle acceleration and gamma rays. Two important techniques of laser proton interactions including target normal sheath acceleration (TNSA) and radiation pressure acceleration (RPA) are discussed in detail, along with their applications in the field of medicine. An analytical framework is developed for laser beat-wave and wakefield excitation of plasma waves and subsequent acceleration of electrons. The book covers parametric oscillator model and studies the coupling of laser light with collective modes.
