本书涉及激光等离子体相互作用过程中发生的众多等离子体过程的基础物理学。主题涉及基础等离子体物理学和应用物理学。作者从持续时间从纳秒到飞秒的高功率激光器的基本原理入手，然后通过描述电离、众所周知的传输系数（电导率和导热率、扩散、粘度、能量传输等）、德拜长度、等离子体振荡和激光诱导等离子体介质的特性，构建了等离子体物理学的简介。本书包含用于描述流体动力学和动力学现象的等离子体动力学方程，并通过计算机模拟处理粒子动力学。讨论了未磁化等离子体中小振幅电磁场的有质动力。然而，对于强激光束，人们应该获得相对论有质动力的新表达式，而这在本书中是完全没有的。此外，在激光等离子体相互作用中会产生强磁场，这将极大地改变相对论有质动力表达式。电磁波碰撞吸收及其在不均匀未磁化等离子体中传播的物理原理已经得到了优雅的描述。还讨论了激光的共振吸收现象。开发了参数过程的简单模型，但没有讨论空子/包络孤子。后者通常被认为是调制/丝状不稳定性的可能非线性状态。相反，作者描述了没有激光场的非线性离子声波的 K-dV 方程。非包络离子声孤子的描述已经出现在许多等离子体物理教科书中。这本书包含一个关于真空中自相似等离子体膨胀、双层和带电粒子加速的简短章节。然而，作者没有涉及基于等离子体的高能带电粒子加速器，该加速器涉及短强激光脉冲，并且处于现代等离子体物理学的前沿。有一个很好的章节讨论了磁化等离子体中的激光感应磁场和波。深入描述了惯性约束聚变中具有重要意义的电子能量传输和热波的物理和数学细节。介绍了冲击波和稀疏波的综合研究，并讨论了它们与高功率脉冲激光驱动器的相关性。最后，作者对流体动力学不稳定性（即瑞利-泰勒、里希特迈尔-梅什科夫、开尔文-亥姆霍兹）进行了清晰的描述，这些不稳定性在激光-等离子体相互作用和天体物理学中非常重要。如果作者还能对这些不稳定性的非线性演化进行更物理性的描述，那就太好了，这些不稳定性在实验室和天体物理环境中的手指、气泡和涡流的形成中发挥着重要作用。这本书写得很好，对于从事激光等离子体相互作用和高能天体物理学领域工作的研究生和物理学家来说将是一笔宝贵的财富。它对于教授激光等离子体相互作用的硕士课程也很有用。评论家向感兴趣的读者强烈推荐这本书。 PK舒克拉
This book deals with the fundamental physics of numerous plasma processes that occur during laser plasma interactions. The subject matter is related to both basic plasma physics and applied physics. The author starts with the essentials of high power lasers whose duration ranges from nanoseconds to femtoseconds, and then builds up an introduction to plasma physics by describing ionization, well known transport coefficients (electrical and thermal conductivities, diffusion, viscosity, energy transport etc), Debye length, plasma oscillations and the properties of the laser induced plasma medium. The book contains plasma dynamical equations for describing the hydrodynamic and kinetic phenomena, and treating particle dynamics by computer simulation. The ponderomotive force is discussed for small amplitude electromagnetic fields in an unmagnetized plasma. However, for intense laser beams one should obtain new expressions for the relativistic ponderomotive force, which are totally absent from this book. Furthermore, in laser plasma interactions strong magnetic fields are produced which will drastically modify the relativistic ponderomotive force expressions. The physics of collisional absorption of electromagnetic waves and their propagation in a nonuniform unmagnetized plasma has been elegantly described. The phenomena of the resonance absorption of laser light is also discussed. Simple models for the parametric processes are developed, while there are no discussions of cavitons/envelope solitons. The latter are usually regarded as possible nonlinear states of the modulational/filamentational instabilities. Rather, the author presents a description of a K-dV equation for nonlinear ion-acoustic waves without the laser field. The description of a non-envelope ion-acoustic soliton has already appeared in many plasma physics textbooks. The book contains a short chapter on the self-similar plasma expansion in vacuum, double layers, and charged particle acceleration. However, the author has not touched on the plasma based high energy charged particle accelerators, which involve short intense laser pulses and which are at the frontier of modern plasma physics. There is a nice chapter dealing with laser induced magnetic fields and waves in magnetized plasmas. The physics and mathematical details of the electron energy transport and heat waves, which are of significant interest in inertial confinement fusion, are described in depth. Comprehensive studies of shock waves and rarefaction waves are presented, and their relevance to high power pulsed laser drivers is discussed. Finally, the author has given a lucid description of hydrodynamic instabilities (i.e. the Rayleigh-Taylor, the Richtmyer-Meshkov, the Kelvin-Helmholtz), which are of great importance in laser-plasma interactions and in astrophysics. It would have been nice if the author would have also included a more physical description of the nonlinear evolution of those instabilities which play a significant role in the formation of fingers, bubbles and vortices in laboratories and in astrophysical settings. The book is well written and will serve as a valuable asset for graduate students and physicists working in the area of laser plasma interactions and high energy astrophysics. It should also be useful for teaching masters level courses on laser plasma interactions. The reviewer highly recommends the book to the interested reader. P K Shukla
