No minimum orderDescription
Industrial Applications of Lasers focuses on how lasers have been used for practical applications in industry. This text aims to stimulate the imagination of the readers, who can then evaluate the potential application of lasers to solve their own problems. Comprised of 21 chapters, this book starts with an overview of the fundamental background of lasers, and then discusses the basic principles of how lasers operate. Other chapters provide an understanding of how holograms really work. This text also discusses several topics relevant to lasers, themselves, including the types of practical lasers and laser properties. This book considers laser safety, which is very important for anyone considering a laser application. Finally, this text explores the various developed laser applications, including scribing of ceramics, laser welding and cutting of metals, as well as applications in surveying, alignment, and metrology. This book is a valuable resource to laser technicians, physicists, scientists, researchers, and readers whose interests span a variety of fields.
