Lasers emit coherent electromagnetic radiation, and ever since their invention, they have assumed tremendous importance in the ﬁelds of science, engineering, and technology because of their impact in both basic research as well as various technological applications. Lasers are ubiquitous and can be found in consumer goods such as music players, laser printers,scannersforproductidentiﬁcation, in industries like metal cutting, welding, hole drilling, marking, in medical applications in surgery, and in scientiﬁc applications like in spectroscopy, interferometry, and testing of foundations of quantum mechanics. The scientiﬁc and technological advances have enabled lasers spanning time scales from continuous operation up to as short as a hundred attoseconds, wavelengths spanning almost the entire electromagnetic spectrum up to the X-ray region, power levels into the terawatt region, and sizes ranging from tiny few tens of nanometers to lasers having a length of 270 km. The range of available power, pulse widths, and wavelengths are extremely wide and one can almost always ﬁnd a laser that can ﬁt into the desired application be it material processing, medical application, or in scientiﬁc or engineering discipline. Laser being the fundamental source with such a range of properties and such wide applications, a course on the fundamentals and applications of lasers to both scientists and engineers has become imperative.
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.
Lasers: Fundamentals and Applications provides a coherent presentation of the basic physics behind the way lasers work, their important characteristics, and some of their most important 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 serves as an important textbook for students pursuing undergraduate and graduate courses on lasers and their applications and is expected to help the student understand the basic principles of lasers and how to apply the concepts found within to practical situations.
A large number of numerical examples scattered throughout the book will not only help students to have a better appreciation of the concepts and solve the problems at the end of each chapter but will also help students gain a better understanding of the basics and apply 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
