This book discusses many advances in optical physic, and is aimed at advanced undergraduates taking courses in atomic physics, or graduate students in the fields of lasers, astrophysics, and physical chemistry. The book is intended mainly for experimentalists, and the interaction of electromagnetic radiation with free atoms is introduced using classical or semi-classical calculations wherever possible. Topics discussed include the spontaneous emission of radiation, stimulated transitions and the properties of gas and turnable dye lasers, and the physics and applications of resonance fluorescence, optical double resonance, optical pumping, and atomic beam magnetic resonance experiments.

Experimental spectroscopic techniques, especially those involving lasers, have wide-ranging applications in the fields of physics, medicine, electronics, and chemistry. Keeping in mind the importance of spectroscopic detection and characterization of atomic and molecular species, this book, now in its Second Edition, is updated. It deals with both the conventional and modern experimental techniques related to atoms, spectroscopy and lasers. It discusses the recent innovations, types and operating principles of lasers and laser systems. A section on Fiber Laser has been added in the new edition of the book. Recent developments in planetary detection of atoms and molecules by Laser Induced Breakdown Spectroscopy (LIBS) has prompted the inclusion of a section on LIBS on planet Mars along with its applications. Primarily intended as a text for undergraduate and postgraduate students of Physics in various Indian universities, this uptodate book would be immensely useful also for both undergraduate and postgraduate students in Chemistry, Astrophysics, Metallurgy and Material Science, and Geology and Mining. Key Features Coverage is quite extensive to cater to students of most Indian universities—with detailed discussions on atoms, spectroscopy and lasers. Gives special emphasis on modern aspects of spectroscopy such as laser cooling of atoms. Contains more than 140 diagrams to illustrate the concepts better.

Principles of Laser Spectroscopy and Quantum Optics is an essential textbook for graduate students studying the interaction of optical fields with atoms. It also serves as an ideal reference text for researchers working in the fields of laser spectroscopy and quantum optics. The book provides a rigorous introduction to the prototypical problems of radiation fields interacting with two- and three-level atomic systems. It examines the interaction of radiation with both atomic vapors and condensed matter systems, the density matrix and the Bloch vector, and applications involving linear absorption and saturation spectroscopy. Other topics include hole burning, dark states, slow light, and coherent transient spectroscopy, as well as atom optics and atom interferometry. In the second half of the text, the authors consider applications in which the radiation field is quantized. Topics include spontaneous decay, optical pumping, sub-Doppler laser cooling, the Heisenberg equations of motion for atomic and field operators, and light scattering by atoms in both weak and strong external fields. The concluding chapter offers methods for creating entangled and spin-squeezed states of matter. Instructors can create a one-semester course based on this book by combining the introductory chapters with a selection of the more advanced material. A solutions manual is available to teachers. Rigorous introduction to the interaction of optical fields with atoms Applications include linear and nonlinear spectroscopy, dark states, and slow light Extensive chapter on atom optics and atom interferometry Conclusion explores entangled and spin-squeezed states of matter Solutions manual (available only to teachers)

With contributions by numerous experts

A wide-ranging review of modern techniques in atomic and molecular spectroscopy. A brief description of atomic and molecular structure is followed by the relevant energy structure expressions. A discussion of radiative properties and the origin of spectra leads into coverage of X-ray and photoelectron spectroscopy, optical spectroscopy, and radiofrequency and microwave techniques. The treatment of laser spectroscopy investigates various tunable sources and a wide range of techniques characterized by high sensitivity and high resolution. Throughout this book, the relation between fundamental and applied aspects is shown, in particular by descriptions of applications to chemical analysis, photochemistry, surface characterisation, environmental and medical diagnostics, remote sensing and astrophysics.

Spectroscopy is the study of electromagnetic radiation and its interaction with solid, liquid, gas and plasma. It is one of the widely used analytical techniques to study the structure of atoms and molecules. The technique is also employed to obtain information about atoms and molecules as a result of their distinctive spectra. The fast-spreading field of spectroscopic applications has made a noteworthy influence on many disciplines, including energy research, chemical processing, environmental protection and medicine. This book aims to introduce students to the topic of spectroscopy. The author has avoided the mathematical aspects of the subject as far as possible; they appear in the text only when inevitable. Including topics such as time-dependent perturbation theory, laser action and applications of Group Theory in interpretation of spectra, the book offers a detailed coverage of the basic concepts and applications of spectroscopy.
