Laser Processing and Chemistry gives an overview of the fundamentals and applications of laser-matter interactions, in particular with regard to laser material processing. Special attention is given to laser-induced physical and chemical processes at gas-solid, liquid-solid, and solid-solid interfaces. Starting with the background physics, the book proceeds to examine applications of laser techniques in micro-machining, and the patterning, coating, and modification of material surfaces. This fourth edition has been revised and enlarged to cover new topics such as 3D microfabrication, advances in nanotechnology, ultrafast laser technology and laser chemical processing (LCP). Graduate students, physicists, chemists, engineers, and manufacturers alike will find this book an invaluable reference work on laser processing.

The complete guide to understanding and using lasers in material processing! Lasers are now an integral part of modern society, providing extraordinary opportunities for innovation in an ever-widening range of material processing and manufacturing applications. The study of laser material processing is a core element of many materials and manufacturing courses at undergraduate and postgraduate level. As a consequence, there is now a vast amount of research on the theory and application of lasers to be absorbed by students, industrial researchers, practising engineers and production managers. Written by an acknowledged expert in the field with over twenty years' experience in laser processing, John Ion distils cutting-edge information and research into a single key text. Essential for anyone studying or working with lasers, Laser Processing of Engineering Materials provides a clear explanation of the underlying principles, including physics, chemistry and materials science, along with a framework of available laser processes and their distinguishing features and variables. This book delivers the knowledge needed to understand and apply lasers to the processing of engineering materials, and is highly recommended as a valuable guide to this revolutionary manufacturing technology. The first single volume text that treats this core engineering subject in a systematic manner Covers the principles, practice and application of lasers in all contemporary industrial processes; packed with examples, materials data and analysis, and modelling techniques

Laser processing of solid materials has been commonly performed in gas ambient. Having the workpiece immersed into liquid, having a liquid film on it, or soaking the material with liquid gives several advantages such as removal of the debris, lowering the heat load on the workpiece, and confining the vapour and plasma, resulting in higher shock pressure on the surface. Introduced in the 1980s, neutral liquids assisted laser processing (LALP) has proved to be advantageous in the cutting of heat-sensitive materials, shock peening of machine parts, cleaning of surfaces, fabrication of micro-optical components, and for generation of nanoparticles in liquids. The liquids used range from water through organic solvents to cryoliquids. The primary aim of Handbook of Liquids-Assisted Laser Processing is to present the essentials of previous research (tabulated data of experimental conditions and results), and help researchers develop new processing and diagnostics techniques (presenting data of liquids and a review of physical phenomena associated with LALP). Engineers can use the research results and technological innovation information to plan their materials processing tasks. Laser processing in liquids has been applied to a number of different tasks in various fields such as mechanical engineering, microengineering, chemistry, optics, and bioscience. A comprehensive glossary with definitions of the terms and explanations has been added. The book covers the use of chemically inert liquids under normal conditions. Laser chemical processing examples are presented for comparison only. First book in this rapidly growing field impacting mechanical and micro/nano-engineering Covers different kinds of liquid-assisted laser processing of a large variety of materials Covers lasers emitting from UV to IR with pulse lengths down to femtoseconds Reviews over 500 scientific articles and 300 inventions and tabulates their main features Gives a qualitative and quantitative description of the physical phenomena associated with LALP Tabulates 61 parameters for 100 liquids Glossary of over 200 terms and abbreviations

This volume discusses both the practical and theoretical aspects of energy beam materials processing. It highlights the recent advances in the use of beams and incoherent light sources to enhance or modify chemical processes at solid surfaces. Special attention is given to the latest developments in the use of ion, electron and photon beams, and on laser-assisted process chemistry. Thin film and surface and interface reactions as well as bulk phase transformations are discussed. Practical technological details and the criteria for present and future applications are also reviewed. The papers collected in this volume reflect the continuing strong interest and variety of development in this field.

Laser processing is now a rapidly increasing field with many real and potential applications in different areas of technology such as micromecha­ nics, metallurgy, integrated optics, and semiconductor device fabrication. The neces s ity for such soph i st i cated 1 i ght sources as 1 asers is based on the spatial coherence and the monochromaticity of laser light. The spatial coherence permits extreme focussing of the laser light resulting in the availability of high energy densities which can be used for strongly loca­ lized heat- and chemical-treatment of materials, with a resolution down to 1 ess than 1 lJIll. When us i ng pul sed or scanned cw-l asers, 1 oca 1 i zat i on in time is also possible. Additionally, the monochromaticity of laser light allows for control of the depth of heat treatment and/or selective, nonthermal bond breaking - within the surface of the material or within the molecules of the surrounding reactive atmosphere - simply by tuning the laser wavelength. These inherent advantages of laser light permit micromachining of materials (drilling, cutting, welding etc. ) and also allow single-step controlled area processing of thin films and surfaces. Processes include structural transformation (removal of residual damage, grain growth in polycrystalline material, amorphization, surface hardening etc. ), etching, doping, alloying, or deposition. In addition, laser processing is not 1 imited to planar substrates.

The papers in this volume cover all aspects of laser assisted surface processing ranging from the preparation of high-Tc superconducting layer structures to industrial laser applications for device fabrication. The topics presented give recent results in organometallic chemistry and laser photochemistry, and novel surface characterization techniques. The ability to control the surface morphology by digital deposition and etching shows one of the future directions for exciting applications of laser surface processing, some of which may apply UV and VUV excitation. The understanding of elementary proceses is essential for the design of novel deposition methods, with diamond CVD being an outstanding example. The high quality of these contributions once again demonstrates that the E-MRS is an efficient forum for interaction between research workers and industry.

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.
