Lasers: Fundamentals and Applications [Paperback]

Ever since their invention in 1960, lasers have assumed tremendous importance in the fields of science, engineering and technology because of their use both in basic research and in various technological applications.?Lasers: Theory and Applications 2nd Edition?will provide a coherent presentation of the basic physics behind the working of the laser along with some of their most important applications. Numerical examples are scattered throughout the book for helping the student gain a better appreciation of the concepts and problems at the end of each chapter and provides the student?a better understanding of the basics and help in applying the concepts to practical situations. This book serves as a text in a course on lasers and their applications for students majoring in various disciplines such as Physics, Chemistry and Electrical Engineering.Updated and revised, this second edition provides a coherent presentation of the basic physics behind lasers, along with some of their most important applications. Numerical examples are scattered throughout the book, and problems are included at the end of each chapter.
