Lasers are now recognized as practical alternatives to conventional techniques for many industrial applications. This book has an international bias towards the practical aspects of laser applications. After reviewing the basic theory, it provides an insight into equipment technology and applications. The major types of industrial laser are presented, including pulsed, continuous wave and Q-switched Nd: YAG lasers and gas and excimer lasers. Both general and specific materials processing applications are covered, including machining, drilling, cutting, welding and surface treatment. The editors and contributors are drawn from industry, equipment manufacturers and research groups to provide the reader with the range and depth of expertise necessary in this increasingly important field.
