Laser Material Processing is an introductory book on the application of lasers to cutting, welding, and the many new processes in surface treatment. Background information on surface treatment processes is provided to give the reader a real understanding of the process mechanisms, method of application, and industrial potential. Additionally, there are sections on basic optics, theoretical modelling, automation and safety. The material presented is based upon a course Professor Steen presents to groups from British Aerospace, and to his own MSc students in laser technology. This unique combination of topics has excellent potential as university course material for undergraduate, graduate, and postgraduate studies in optoelectronics, laser processing, and advanced manufacturing. Engineers and technicians in these areas will also find the book a welcome source of information on the rapidly expanding use of industrial lasers.
