This book, written by one of the pioneers of laser theory, is now considered a classic by many laser physicists. Originally published in the prestigious Encyclopedia of Physics series, it is now being republished in paperback to make it available not only to professors and scientists, but also to students. It presents a thorough treatment of the theory of laser resonators, the quantum theory of coherence, and the quantization of electromagnetic fields. Especial emphasis is placed on the quantum-mechanical treatment of laser light by means of quantum-mechanical Langevin equations, the density matrix equation, and the Fokker-Planck equation. The semiclassical approach and the rate equa tion approach are also presented. The principles underlying these approaches are used to derive the relevant equations, from which, in turn, the various properties of laser light are derived. Preface. The concept of the laser came into existence more than a decade ago when SCHAWLOW and TOWNES showed that the maser principle could be extended to the optical region. Since then this field has developed at an incredible pace which hardly anybody could have foreseen. The laser turned out to be a meeting place for such different disciplines as optics (e. g. spectroscopy). optical pumping, radio engineering, solid state physics, gas discharge physics and many other fields. The underlying structure of the laser theory is rather simple.

This book provides a unified and complete theory for semiconductor lasers, covering topics ranging from the principles of classical and quantum mechanics to highly advanced levels for readers who need to analyze the complicated operating characteristics generated in the real application of semiconductor lasers. The author conducts a theoretical analysis especially on the instabilities involved in the operation of semiconductor lasers. A density matrix into the theory for semiconductor lasers is introduced and the formulation of an improved rate equation to help understand the mode competition phenomena which cause the optical external feedback noise is thoroughly described from the basic quantum mechanics. The derivation of the improved rate equation will allow readers to extend the analysis for the different types of semiconductor materials and laser structures they deal with. This book is intended not only for students and academic researchers but also for engineers who develop lasers for the market, as the advanced topics covered are dedicated to real problems in implementing semiconductor lasers for practical use.

The articles in this book review recent developments in the microscopic theory of optical and electronic semiconductor properties. Many advances in this active field are intimately related to the work of Hartmut Haug and his coworkers. At the occasion of Haug's 60th birthday, a number of current and/or former members of his research team review the current state-of-the-art. Topics include the quantum kinetics of electrons, phonons and photons, coherent optical effects, quantum transport, ballistic motion, microscopic semiconductor laser theory with special emphasis on microlasers, symmetry aspects of laser excited semiconductors, as well as a review of the two-dimensional Wigner crystal in a strong magnetic field. The articles present the material in sufficient detail to be understandable by advanced graduate students and researchers who have a good background in quantum mechanics. Contents:Early Stage of the Coulomb Kinetics: Carrier Screening and Optical Dephasing (K El Sayed)Urbach Tail, Optical Stark Effect, and Their Connection to Quantum Kinetic Equations (C Ell)Coherent Dynamics of Semiconductor Heterostructures (S W Koch et al.)Quantum Kinetic Theory of the Semiconductor Laser (K Henneberger & S W Koch)Theory of Semiconductor Microcavity Lasers (F Jahnke et al.)Excitonic Gain Processes in ZnSe (I Galbraith)Symmetry Aspects of Multi-Band Semiconductors Interacting with Light Fields (M Lindberg)Effect of Image Charges on the Electron-Hole-Pair States in Semiconductor Microstructures (D B Tran Thoai)Ballistic and Dissipative Motions of the Classical Polaron (L Bányai)The s-Wave Coulomb-Green Function (L Bányai)The Two-Dimensional Wigner Crystal in a Strong Magnetic Field (R Côté)Bipolariton Concept for an Excitonic Molecule (A L Ivanov) Readership: Condensed matter physicists and engineers. keywords:Semiconductor Optics;Semiconductor Laser Theory;Excitons;Greens Functions;Wigner Crystal;Coherent Effects;Carrier Screening;Coulomb Kinetics

In this monograph, the authors offer a comprehensive examination of the latest research on Laser Chemical Vapor Deposition (LCVD). Chapters explore the physics of LCVD as well as the principles of a wide range of related phenomena-including laser-matter interactions, heat transfer, fluid flow, chemical kinetics, and adsorption. With this reference, researchers will discover how to apply these principles to developing theories about various types of LCVD processes; gain greater insight into the basic mechanisms of LCVD; and obtain the ability to design and control an LCVD system.

The recent years have been characterized by stormy social protests throughout the world. These protests have some commonalities, but at the same time, their sociopolitical, psychological, and economic contexts differ essentially. An important class of such protests is known as color revolutions. The analysis of these events in social and political literature is characterized by huge diversity of opinions. We remark that the sociopolitical perturbations under consideration are characterized by the cascade dynamics leading to the exponential amplification of coherent social actions. In quantum physics, such exponential and coherent amplification is the basic feature of laser’s functioning. (“Laser” is acronym for light amplification by stimulated emission of radiation). In this book we explore the theory of laser to model aforementioned waves of social protests, from color revolutions to Brexit and Trump’s election. We call such social processes Stimulated Amplification of Social Actions (SASA), but to keep closer to the analogy with physics we merely operate with the term “social laser.”
