Book Description
CO2 Lasers: Effects and Applications examines and summarizes the important applications of the device in different areas of study like physics, chemistry, and engineering. In some parts of the book, the reader is assumed to be knowledgeable in university level mathematics or some specialized area in physics or chemistry. The book consists of 10 chapters where the first two establish the general concepts on lasers and CO2 lasers, respectively. Chapter 3 takes the reader further and presents a comprehensive review of optical components for use such as detectors, windows, and mirrors. Because the CO2 laser is mostly used as a heat source, the theory of laser-surface heating is relevant in the discussion. This theory is presented in Chapter 4. Chapters 5 and 6 meanwhile present a summary of observations on cutting, welding, and some related topics. The following chapters discuss the different applications of CO2 lasers in different areas and processes. Some of these applications include in the generation of thermal effect, laser deposition of thin films, spectroscopy, laser photochemistry, and meteorology and communication systems. The text is a good source of reference to both students and scientists in the areas of physics, chemistry, and engineering.

Book Description
Modern manufacturing industry is focusing its interests on the potential offered by the laser, in combination with other new technologies such as optical fibres, automation, computing and flexible manufacturing systems, to give new and powerful methods for non-destructive testing, in-process quality assurance, laser material processing and process control, and laser robotics. The greatest opportunities for the laser are in those areas where flexibility, automation, CAD/CAM integration, precision, cost reduction, and time to market are important factors. The examples covered here are mainly drawn from the automotive industry, where all these factors are imperative, and where the CO2, Nd-YAG and excimer laser sources are already making their contribution to the manufacturing process.

Book Description
It has often been said that the laser is a solution searching for a problem. The rapid development of laser technology over the past dozen years has led to the availability of reliable, industrially rated laser sources with a wide variety of output characteristics. This, in turn, has resulted in new laser applications as the laser becomes a familiar processing and analytical tool. The field of materials science, in particular, has become a fertile one for new laser applications. Laser annealing, alloying, cladding, and heat treating were all but unknown 10 years ago. Today, each is a separate, dynamic field of research activity with many of the early laboratory experiments resulting in the development of new industrial processing techniques using laser technology. Ten years ago, chemical processing was in its infancy awaiting, primarily, the development of reliable tunable laser sources. Now, with tunability over the entire spectrum from the vacuum ultraviolet to the far infrared, photo chemistry is undergoing revolutionary changes with several proven and many promising commercial laser processing operations as the result. The ability of laser sources to project a probing beam of light into remote or hostile environments has led to the development of a wide variety of new analytical techniques in environmental and laboratory analysis. Many of these are reviewed in this book.

Book Description
Evaluations were made using an infrared non-destructive testing technique employing scan laser heating of the specimen. Thermal images were obtained with a newly developed two-dimensional reflective scanner, coupled to a 50 watt CO2 laser to irradiate the specimen and a thermal imaging camera to view the specimen's irradiated surfaces. The technique showed a capability of providing a real time non-destructive test for subsurface defects in a variety of materials and structures. It allows the laser heat source and infrared camera to be remotely positioned from the specimen under test, making it possible to examine large specimens.

Book Description
High power lasers and their applications in production technology have experienced a vivid development during the last decades and now offer improved performance of classical applications in cutting or welding. Processes that are used since a long time have been improved considerably, for instance hardening. More and more new applications have been developed for instance 3D-printing of metals or forming with laser assistance. Therefore, it is important for production engineers to understand the laser technology and explore how it can be used to enhance production speed, quality, and reduce cost.This book treats the basic principles underlying laser technology, long-time-used equipment and processes but also the most recent improvements and applications, then compares it with the competing conventional technologies. Each of these two parts is preceded by tutorials that inform the reader about the physical basis of the respective technologies. In addition, hazards of these technologies and respective protection are treated for both cases. The book concludes with a detailed comparison of competing technologies and lasers to give a prognosis on the future of lasers in manufacturing. It is written in a style that can be read by people without a broad physical basis and avoids the use of derivations and equations but explains all the material in an easily understandable way in simple words.

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.
