Quantum Electronics for Atomic Physics provides a course in quantum electronics for researchers in atomic physics and other related areas such as telecommunications. The book covers the usual topics, such as Gaussian beams, lasers, nonlinear optics and modulation techniques, but also includes a number of areas not usually found in a textbook on quantum electronics. Among the latter are such practical matters as the enhancement of nonlinear processes in a build-up cavity or periodically polled waveguide, impedance matching into a cavity, laser frequency stabilization (including servomechanism theory), astigmatism in ring cavities, and frequency locking a laser to an atomic or molecular line. The second edition includes a new complete chapter on optical waveguide theory, fiber optic components and fiber lasers. Other updates include new coverage of mode locked fiber lasers, comb generation in a micro-resonator, and periodically poled optical waveguides.

"Quantum Electronics for Atomic Physics" discusses theoretical and practical aspects for generating and manipulating laser radiation. It is aimed at graduate students and researchers in atomic physics laboratories and includes topics not usually found in quantum electronics textbooks that are often aimed at telecommunication workers.

Introduction to Quantum Electronics is based on a one-semester lecture of electrical engineering for German students. The book is an introduction to the fundamentals of lasers and masers and a presentation of the principles of physics, their theory, and methods of analysis that seek to analyze, explain, and quantify related important phenomena. The properties of a laser is then discussed, the author comparing it to the properties of the maser. Although masers are based on the same physical properties as that of the lasers, masers amplify microwaves by induced emission. How the laser is amplified, its power and frequency of oscillation, and which media are suitable for lasers are analyzed. Descriptions of the laser take more emphasis as it is considered to have more technical applications than the maser. An example given is the operation of the gas laser, because it exhibits coherence in time and space, considered as the most important quality of laser beams. Physicists, students, and academicians in the field of electrical engineering and quantum electronics will find that this book addresses many of their interests.

Quantum Electronics is that discipline of Physics which deals with the impact of quantum mechanics on the specific behavior of electrons in elements or that of any matter. To get an in depth understanding of the quantum electronics as a whole, it is required that atomic physics, which studies and explains the inner workings of atoms in matter, has to be understood very well. Atomic Physics is widely acclaimed as the most active of the testing grounds of the quantum theory and is rightly the field of extensive research for both its contribution to quantum electronics and technology in general, as well as for its contribution to all physics fundamentally. Not only quantum electronics, but a plethora of other disciplines are heavily indebted to Atomic Physics in that regard, some of them are quantum chemistry, astrophysics, solid-state physics, laser physics etc. According to one of the greatest pioneers of quantum mechanics, Mr. Feynman, if for some reason, all the information regarding science that is known to man today has to go except only one sentence that could be passed on to the next generation of creatures, then the most important of all information to fit into that one sentence would be the idea of atoms or atomic hypothesis / fact, whichever you want to call it - that describes little particles that are under constant movement and attracting each other if apart and repelling each other when squeezed- With a little bit of thinking and imagination applied to that one sentence, one can easily observe the huge information as well as the great evaluation made about our world! The primary task of Atomic Physics is to determine the wave functions as well as the energies emitted out of the quantized electron, leaving everything else related to the nucleus is left to Nuclear Physics to determine. So, for concept building we need to put stress on the basics of atomic physics before moving on the applications of Quantum Electronics.

Quantum mechanics is the most successful theory for describing the micro-world of photons, atoms, and their aggregates. It is behind much of the successes of the modern technology. It has deep philosophical implications to the fundamental nature of material reality. A few decades ago it was also realized that it is connected to the computer science and information theory. With this understanding was born the new disciplines of quantum computing and quantum communication. The current book introduces the very exciting area of quantum communication which lies at the intersection of quantum mechanics, information theory, and atomic physics. The relevant concepts of these disciplines are explained and their implication for the task of unbreakably secure communication is elucidated. Mathematical formulation of various approaches are explained and attempt has been made to keep the exposition self-contained.

Principles of Quantum Electronics focuses on the concept of quantum electronics as the application of quantum theory to engineering problems. It examines the principles that govern specific quantum electronics devices and presents their theoretical applications to typical problems. Comprised of 10 chapters, this book starts with an overview of the Dirac formulation of quantum mechanics. This text then considers the derivation of the formalism of field quantization and discusses the properties of photons and phonons. Other chapters examine the interaction between the electromagnetic field and charged particles. This book discusses as well the interaction of radiation with free and bound electrons, with focus on the spontaneous and stimulated emission of radiation by bound electrons. The final chapter provides the investigation that Maxwell's theory can be regarded as the quantum theory of a single photon. This book is a valuable resource for graduate students, specialists, and engineers who are interested in the field of quantum electrodynamics.

Quantum Communications in New Telecommunications Systems Computers are quickly making the transition from silicon towards miniaturization, which now risks reaching its limits as dictated by the laws of physics. Quantum communications are the answer to post-silicon computers. The main applications for quantum communications in the domain of telecommunications are beginning to appear, with some commercial applications already on the market. This book explores the technological advances in quantum communications with a special focus on telecommunications systems. The authors provide a comprehensive state of the art on quantum communications and quantum signal processing. The reader will learn about the advantages, current applications and future prospects of quantum technology.

The book provides an overview of the most advanced quantum informational geometric techniques, which can help quantum communication theorists analyze quantum channels, such as security or additivity properties. Each section addresses an area of major research of quantum information theory and quantum communication networks. The authors present the fundamental theoretical results of quantum information theory, while also presenting the details of advanced quantum ccommunication protocols with clear mathematical and information theoretical background. This book bridges the gap between quantum physics, quantum information theory, and practical engineering.
