This text treats laser light as a universal tool to control matter at the atomic and molecular level, one of the most exciting applications of lasers. Lasers can heat matter, cool atoms to ultra-low temperatures where they show quantum collective behaviour, and can act selectively on specific atoms and molecules for their detection and separation.

Focusing on atom-light interactions and containing numerous exercises, this in-depth textbook prepares students for research in a fast-growing field.

Due to the rapid progress in laser technology a wealth of novel fundamental and applied applications of lasers in atomic and plasma physics have become possible. This book focuses on the interaction of high intensity lasers with matter. It reviews the state of the art of high power laser sources, intensity laser-atom and laser-plasma interactions, laser matter interaction at relativistic intensities, and QED with intense lasers.

Comprehensive single source for the theory on and status of current research into laser light pressure on atoms and atomic particles. Part I presents the fundamentals of the theory of resonance light pressure, analyzes the basic relations of the radiatio9n force acting on atomic particles, discusses the properties of light pressure for fields of spatial and time structure. Part II describes investigations into the control of atoms and atomic ions by laser pressure, the cooling of atomic beams, and localized atomic ions. It also describes applications of cooled atoms and ions in atomic physics and spectroscopy.

Intended for advanced undergraduates and beginning graduates with some basic knowledge of optics and quantum mechanics, this text begins with a review of the relevant results of quantum mechanics, before turning to the electromagnetic interactions involved in slowing and trapping atoms and ions, in both magnetic and optical traps. The concluding chapters discuss a broad range of applications, from atomic clocks and studies of collision processes, to diffraction and interference of atomic beams at optical lattices and Bose-Einstein condensation.

In this volume, recent contributions on coherence provide a useful perspective on the diversity of various coherent sources of emission and coherent related phenomena of current interest. These papers provide a preamble for a larger collection of contributions on ultrashort pulse laser generation and ultrashort pulse laser phenomena. Papers on ultrashort pulse phenomena include works on few cycle pulses, high-power generation, propagation in various media, to various applications of current interest. Undoubtedly, Coherence and Ultrashort Pulse Emission offers a rich and practical perspective on this rapidly evolving field.

We feel a great pleasure in presenting this text book for U.G. and P.G. students and teachers from various Colleges, Institutes, Academies and Universities to improve their depth of knowledge in the related subject. The purpose of this book is to clear introductory concepts about Atomic, Molecular Physics and LASER and understand the basic concepts which are useful for NET, SET, PET and other competitive examination. This book is written in simple and lucid language with large number of essential diagram and equations covers all the aspects in which students have faced various problems in attempting examinations. Each topic provided contents and split into articles, sub-articles, multiple choice questions with answer in bold type, solved numerical, question for self study and unsolved problems for more practice. Furthermore attempts have made to explain everything whenever required. We hope that this book will definitely fulfill all the requirements of the students and they will welcome this edition with satisfaction. We have done our job with great care and caution. However there may be very few printing errors which may have escaped our attention. So we cannot claim to be infallible. We shall grateful to all teacher and students who will be kind enough in pin pointing our follies, which have escaped our attention. We are firmly believe that there is always scope and improvement, suggestions and comments further improvement will be highly appreciated and gratefully acknowledged from worth teachers, expert professors and student will be received.

Keeping abreast of the latest techniques and applications, this new edition of the standard reference and graduate text on laser spectroscopy has been completely revised and expanded. While the general concept is unchanged, the new edition features a broad array of new material, including applications in chemical analysis, medical diagnostics, and engineering. No other book with such a broad scope is available. The author is one of the most renowned experts in this area. The book is well illustrated, and is supplemented by an extensive set of references. It will benefit all students and scientists working in the field.
