Book Description
This book, written by one of the pioneers of laser theory, is now considered a classic by many laser physicists. Originally published in the prestigious Encyclopedia of Physics series, it is now being republished in paperback to make it available not only to professors and scientists, but also to students. It presents a thorough treatment of the theory of laser resonators, the quantum theory of coherence, and the quantization of electromagnetic fields. Especial emphasis is placed on the quantum-mechanical treatment of laser light by means of quantum-mechanical Langevin equations, the density matrix equation, and the Fokker-Planck equation. The semiclassical approach and the rate equa tion approach are also presented. The principles underlying these approaches are used to derive the relevant equations, from which, in turn, the various properties of laser light are derived. Preface. The concept of the laser came into existence more than a decade ago when SCHAWLOW and TOWNES showed that the maser principle could be extended to the optical region. Since then this field has developed at an incredible pace which hardly anybody could have foreseen. The laser turned out to be a meeting place for such different disciplines as optics (e. g. spectroscopy). optical pumping, radio engineering, solid state physics, gas discharge physics and many other fields. The underlying structure of the laser theory is rather simple.

Book Description
The revised edition of this important reference volume presents an expanded overview of the analytical and numerical approaches employed when exploring and developing modern laser materials processing techniques. The book shows how general principles can be used to obtain insight into laser processes, whether derived from fundamental physical theory or from direct observation of experimental results. The book gives readers an understanding of the strengths and limitations of simple numerical and analytical models that can then be used as the starting-point for more elaborate models of specific practical, theoretical or commercial value. Following an introduction to the mathematical formulation of some relevant classes of physical ideas, the core of the book consists of chapters addressing key applications in detail: cutting, keyhole welding, drilling, arc and hybrid laser-arc welding, hardening, cladding and forming. The second edition includes a new a chapter on glass cutting with lasers, as employed in the display industry. A further addition is a chapter on meta-modelling, whose purpose is to construct fast, simple and reliable models based on appropriate sources of information. It then makes it easy to explore data visually and is a convenient interactive tool for scientists to improve the quality of their models and for developers when designing their processes. As in the first edition, the book ends with an updated introduction to comprehensive numerical simulation. Although the book focuses on laser interactions with materials, many of the principles and methods explored can be applied to thermal modelling in a variety of different fields and at different power levels. It is aimed principally however at academic and industrial researchers and developers in the field of laser technology.

Book Description
A comprehensive treatment of the fundamentals of optical detection theory. Laser system applications are becoming more numerous, particularly in the fields of communications and remote sensing. This book addresses the theoretical aspects of optical detection and associated phenomenologies, describing the fundamental optical, statistical, and mathematical principles of the modern laser system. The book is especially valuable for its extensive treatment of direct detection statistics, which has no analog in radar detection theory and which has never before been compiled in a cohesive manner in a single book.

Book Description
In this monograph, the authors offer a comprehensive examination of the latest research on Laser Chemical Vapor Deposition (LCVD). Chapters explore the physics of LCVD as well as the principles of a wide range of related phenomena-including laser-matter interactions, heat transfer, fluid flow, chemical kinetics, and adsorption. With this reference, researchers will discover how to apply these principles to developing theories about various types of LCVD processes; gain greater insight into the basic mechanisms of LCVD; and obtain the ability to design and control an LCVD system.

Book Description
This book considers some general laser-induced processes that are involved in laser-matter interactions. A brief review is presented about a very interesting application of laser beams in the fields of materials science: the growth of zinc oxide (ZnO) nanostructured films by Pulsed Laser Deposition (PLD). In addition, safe and precise cavity detection, especially of dangerous or inaccessible voids, is essential to safe production in a working mine. The advantages and disadvantages of laser detection systems are analysed, and a combination of laser scanning techniques and conventional survey methodology is proposed. Other chapters in this book present an overview on laser cladding, a discussion of the applications of structured laser beams in laser refractography technology, a review of some fundamentals of laser-induced breakdown spectroscopy (LIBS) and an analysis of laser forming of steel parts by means of diode lasers.

Book Description
Laser Machining: Theory and Practice addresses state-of-the-art laser machining in a way useful for research- ers, academicians and practitioners, particularly manufacturing engineers, who are considering lasers as a solution to the machining requirements of their factories and plants. This book provides detailed information on the theory behind laser machining, as well as its requirements, uses and applications. In order to place laser machining in its correct context, the author begins with an overview of conventional material removal processes and go on to describe in detail the physical mechanisms involved in lasers, the different types of lasers involved in laser machining, and laser machining systems, which include optics, positioning systems, manipulators, etc. The theoretical treatment of the laser includes a section on the basics of heat transfer and fluid mechanics, and analyses of one, two and three-dimensional laser machining processes. The book closes with a description of state-of-the-art laser machining applications in research and industrial practice.
