Lasers

Lasers: Fundamentals and Applications, serves as a vital textbook to accompany undergraduate and graduate courses on lasers and their applications. Ever since their invention in 1960, lasers have assumed tremendous importance in the fields of science, engineering and technology because of their diverse uses in basic research and countless technological applications. This book provides a coherent presentation of the basic physics behind the way lasers work, and presents some of their most important applications in vivid detail.

After reading this book, students will understand how to apply the concepts found within to practical, tangible situations. This textbook includes worked-out examples and exercises to enhance understanding, and the preface shows lecturers how to most beneficially match the textbook with their course curricula. The book includes several recent Nobel Lectures, which will further expose students to the emerging applications and excitement ofworking with lasers.

Students who study lasers, laser applications, and optics and lasers will find this book to be an invaluable contribution to their understanding of the subject.

Topics included and discussed in detail include:

laser rate equations

semiclassical theory of lasers

optical resonators

properties of laser beams

fiber lasers
