Applications of lasers in materials processing have been evolving since the development (first demonstration) of the laser in 1960. The early applications focused on processes such as welding, machining, and heat treatment. Newer processes that have evolved over the years include laser forming, shock peening, micromachining, and nanoprocessing. This book provides a state-of-the-art compilation of material in the major application areas and is designed to provide the background needed by graduate students to prepare them for industry; researchers to initiate a research program in any of these areas; and practicing engineers to update themselves and gain additional insight into the latest developments in this rapidly evolving field.
