Summary:
Laser Fundamentals provides a clear and comprehensive introduction to the physical and engineering principles of laser operation and design. Simple explanations, based throughout on key underlying concepts, lead the reader logically from the basics of laser action to advanced topics in laser physics and engineering. Much new material has been added to this second edition, especially in the areas of solid-state lasers, semiconductor lasers, and laser cavities. The new edition contains a new chapter on laser operation above threshold, including extensive discussion of laser amplifiers. The clear explanations, worked examples, and many homework problems will make this book invaluable to undergraduate and first-year graduate students in science and engineering taking courses on lasers. The summaries of key types of lasers, the use of many unique theoretical descriptions, and the extensive bibliography will also make this a valuable reference work for researchers.
• Unique approach to understanding lasers
• Useful descriptions and data tables of 23 types of commercial lasers
• No background of physics or engineering required, just a knowledge of calculus and simple differential equations

From the Publisher
"Laser Cladding reviews the parameters, techniques and equipment, process modeling and control, and the physical metallurgy of alloying and solidification during laser cladding. The authors clarify the interconnections laser cladding has with CAD/CAM design; automation and robotics; sensors, feedback, and control; physics, material science, heat transfer, fluid dynamics, and powder metallurgy to promote further development and improved process quality of this growing technology. As the first book entirely dedicated to the topic, it also offers a history of its development and a guide to applications and market opportunities." While a considerable part of Laser Cladding is dedicated to industrial applications, this volume brings together valuable information illustrated with real case studies based on the authors' vast experience, research, and analysis in the field to provide a timely source for both academia and industry.
Synopsis
Laser cladding uses a laser heat source to deposit a thin layer of metal on a substrate. With the reduced cost of laser systems, and the effectiveness of such techniques as powder injection, laser material processing has grown substantially. The authors (mechanical engineering, U. of Waterloo, Canada) examine present and future applications of laser cladding, give a basic overview including comparisons with other methods of cladding, and describe equipment, process modeling, process control, physical metallurgy and materials systems, and safety issues of the process and materials. They include information on the physics of the process, CAD/CAM systems, types of lasers, powder feeders and delivery systems, positioning devices, and controllers including those based on fuzzy logic.

.: Laser Cladding :.
Capitalizing on the rapid growth and reduced costs of laser systems, laser cladding is gaining momentum, and in some instances replacing conventional techniques of depositing thin films because it can accommodate a great variety of materials, achieve uniform thickness and precise widths of layers, and provide improved resistance to wear and corrosion in the final product. Laser cladding technology also offers a revolutionary layered manufacturing and prototyping technique that can fabricate complex components without intermediate steps.
Laser Cladding reviews the parameters, techniques and equipment, process modeling and control, and the physical metallurgy of alloying and solidification during laser cladding. The authors clarify the interconnections laser cladding has with CAD/CAM design; automation and robotics; sensors, feedback, and control; physics, material science, heat transfer, fluid dynamics, and powder metallurgy to promote further development and improved process quality of this growing technology. As the first book entirely dedicated to the topic, it also offers a history of its development and a guide to applications and market opportunities.
While a considerable part of Laser Cladding is dedicated to industrial applications, this volume brings together valuable information illustrated with real case studies based on the authors' vast experience, and research and analysis in the field to provide a timely source for both academia and industry.
