Laser-Matter Interaction for Radiation and Energy

by Hitendra K. Malik

The interaction of high-power lasers with matter can generate Terahertz radiations that efficiently contribute to THz Time-Domain Spectroscopy and also would replace X-rays in medical and security applications. When a short intense laser pulse ionizes a gas, it may produce new frequencies even in VUV to XUV domain. The duration of XUV pulses can be confined down to the isolated attosecond pulse levels, required to study the electronic re-arrangement and ultrafast processes. Another important aspect of laser-matter interaction is the laser thermonuclear fusion control where accelerated particles also find an efficient use. This book provides comprehensive coverage of the most essential topics, including Electromagnetic waves and lasers THz radiation using semiconducting materials / nanostructures / gases / plasmas Surface plasmon resonance THz radiation detection Particle acceleration technologies X-ray lasers High harmonics and attosecond lasers Laser based techniques of thermonuclear fusion Controlled fusion devices including NIF and ITER The book comprises of 11 chapters and every chapter starts with a lucid introduction to the main topic. Then sub-topics are sedulously discussed keeping in mind their basics, methodology, state-of-the-art and future perspective that will prove to be salutary for readers. High quality solved examples are appended to the chapters for their deep understanding and relevant applications. In view of the nature of the topics and their level of discussion, this book is expected to have pre-eminent potential for researchers along with postgraduate and undergraduate students all over the world.

Laser Metallic Additive Manufacturing Technologies by Thermal-Mechanical Interaction

by Jinzhong Lu Haifei Lu Kaiyu Luo

This book introduces the laser hybrid additive manufacturing technology (LHAM) with alternately thermal and mechanical effects for the high-performance manufacturing of key components. Metal additive manufacturing (AM) technologies have made considerable progress in the basic theoretical field since its invention in the 1970s. However, there are still some difficulties in the coordinated control of the structure and performance, containing the challenges of “structure control” against deformation and cracking of the formed metallic components incurred by internal stress and “performance control” against poor fatigue property of formed metallic components incurred by metallurgical defects. This book surveys the most relevant papers about the influence of laser shock wave on the microstructural evolution, residual stress, metallurgical defect, and mechanical properties that have become the foundation to elucidate the principles and effects of LHAM technology. This book is separated into four parts to fully present the LHAM technology. The first part reviews the background of LHAM technology. The second part explains the theoretical basis of the thermal effects of laser additive manufacturing (LAM) and mechanical effects of laser shock peening (LSP). The other two parts specifically describe the microstructural evolution, residual stress, metallurgical defect, and mechanical properties using LHAM technology. This book benefits the audience in the field of mechanical engineering and materials sciences, since LHAM technology is suitable for the manufacturing and applications of the key components of aero-engine. The analysis in the book helps the audience deeply understand the mechanism of LHAM technology. The authors’ unique thinking about LHAM technology also runs through the book, which may enlighten the audience to further develop LHAM technology.

Laser Physics

by Marc Eichhorn

This textbook originates from a lecture course in laser physics at the Karlsruhe School of Optics and Photonics at the Karlsruhe Institute of Technology (KIT). A main goal in the conception of this textbook was to describe the fundamentals of lasers in a uniform and especially lab-oriented notation and formulation as well as many currently well-known laser types, becoming more and more important in the future. It closes a gap between the measureable spectroscopic quantities and the whole theoretical description and modeling. This textbook contains not only the fundamentals and the context of laser physics in a mathematical and methodical approach important for university-level studies. It allows simultaneously, owing to its conception and its modern notation, to directly implement and use the learned matter in the practical lab work. It is presented in a format suitable for everybody who wants not only to understand the fundamentals of lasers but also use modern lasers or even develop and make laser setups. This book tries to limit prerequisite knowledge and fundamental understanding to a minimum and is intended for students in physics, chemistry and mathematics after a bachelor degree, with the intention to create as much joy and interest as seen among the participants of the corresponding lectures. This university textbook describes in its first three chapters the fundamentals of lasers: light-matter interaction, the amplifying laser medium and the laser resonator. In the fourth chapter, pulse generation and related techniques are presented. The fifth chapter gives a closing overview on different laser types gaining importance currently and in the future. It also contains a set of examples on which the theory learned in the first four chapters is applied and extended.

Laser Radar

by Division on Engineering and Physical Sciences Committee on Review of Advancements in Active Electro-Optical Systems to Avoid Technological Surprise Adverse to U.S. National Security National Research Council

In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.

Laser Refractography

by I. L. Raskovskaya B. S. Rinkevichyus O. A. Evtikhieva

This book describes the basic principles of laser refractography, a flexible new diagnostic tool for measuring optically inhomogeneous media and flows. Laser refractography is based on digital imaging and computer processing of structured laser beam refraction (SLR) in inhomogeneous transparent media. Laser refractograms provide both qualitative and quantitative measurements and can be used for the study of fast and transient processes. In this book, the theoretical basis of refractography is explored in some detail, and experimental setups are described for measurement of transparent media using either 2D (passed radiation) or 3D (scattered radiation) refractograms. Specific examples and applications are discussed, including visualization of the boundary layer near a hot or cold metallic ball in water, and observation of edge effects and micro layers in liquids and gases. As the first book to describe this new and exciting technique, this monograph has broad cross-disciplinary appeal and will be of interest to students and researchers who need to characterize complex fluid behavior.
