Lasers: fundamentals and applications serves as a vital textbook for an undergraduate or a graduate course on lasers and their applications. Ever since the invention of the laser in 1960, lasers have assumed tremendous importance in the fields of science, engineering and technology because of their special characteristics and diverse uses in basic research and countless technological applications. This book provides a coherent presentation of the basic Physics behind the way lasers work, their important characteristics and some of their most important applications. ≪ br/> this book is expected to help the student understand the basic principles of lasers and how to apply the concepts to practical situations. There are a number of numerical examples scattered throughout the book for helping the student to have a better appreciation of the concepts; The problems at the end of each br>Chapter should provide the student with gaining a better understanding of the basics and help in applying the concepts to practical situations. The applications discussed in the book are some of the most important ones making use of the special characteristics possessed by lasers. The book also includes Nobel lectures of several scientists which should give the reader some sense of perspective of the history of the development of the laser and also its applications. ≪ br/> some of the topics discussed in detail include: laser rate equations, semi classical theory of the laser, quantization of the electromagnetic field, coherent state, squeezed state, optical resonators, fiber lasers, semiconductor lasers, optical parametric oscillators, light wave communications, applications of lasers in science and industry. ≪ br/> .
