This book was released on 2012-12-06 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the large majority of the papers presented at the Cooperative Effects Meeting which was held as part of the US Army Sponsored Symposium on New Laser Concepts at Redstone Arsenal, Alabama, from November 30 through December 2, 1976. The motivation for the meeting was to bring together a representative cross-section of research scientists active in related areas of cooperative effects in matter-radiation field interaction and coherent pulse generation and propagation. An emphasis was placed upon the rapidly developing areas of superradiance and superf1uorescence, with a balance between theory and experiment in regard to the choice of speakers. This meeting came at a very fortunate time when new experimental results in metal vapors and gases have just recently been realized. Also represented on the programwereareas dealing with new laser concepts such as the free electron laser and two photon amplifier. A few supplemental papers are included in this volume which were authored by participants at the meeting, but were not present on the agenda, primarily due to limited time. These were included because of their relation to the content of papers which were presented and/or were the subject of discussion among attendees. The meeting consisted of eleven invited papers and two work shop sessions, each with a panel. The order of the papers in this volume generally follows the order of their presentation on the agenda. However, the supplemental papers have been inserted where appropriate.

Available in PDF, EPUB and Kindle. Book excerpt: Cooperative Effects in Optics: Superradiance and Phase Transitions presents a systematic treatment of the modern theory of cooperative optical phenomena-processes in which the behavior of many-body systems of radiators or absorbers is essentially determined by their collective interactions with each other. The book focuses on the theory of collective spontaneous radiation (superradiance) and provides a detailed physical explanation of the mechanism of collective spontaneous emission. It considers numerous models of novel nonequilibrium light-induced phase transitions in a typical quantum electronics system, including two-level atoms interacting with the radiation field and more complex systems of three-level atoms, two-bank semiconductors, and other interatomic interactions with the electrostatic and lattice displacement fields. The book uses some of these models for the interpretation of experimentally observed light-induced critical phenomena. Cooperative Effects in Optics is of great value to research workers in the field of cooperative optical phenomena, especially in the determination of the physical essence of theoretical models developed to describe cooperative effects in multi-atomic systems.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cooperative effect in the radiation process has been studied in for more than half a century. It is important in the sense of both basic physics and applied science. In this work, we study the dynamics of the cooperative spontaneous emission from an ensemble of N atoms which is uniformly excited by absorbing a single photon. We reveal that there are two different regimes in which the system exhibits totally different behaviors. One of them is the superradiance type of behavior: the system decays much quicker than single atom decay, with a decay rate proportional to N(a/R)2, where N is the atom numbers, R is the size of the atom cloud, and a the wavelength. We call it Markovian regime because the sytem does not persist memory effect. The other regime is called non-Markovian regime and the system oscillates with effective Rabi oscillation frequency while slowly decaying with a rate proportional to the photon escaping rate. The effective Rabi oscillation is a new type of dynamics which analogs well known Cavity QED behavior. Particularly in the Markovian regime, we study the system dynamics as a manybody eigenfunction and eigenvalue problem. For a dense cloud, we find analytical solutions for the eigenstates and corresponding eigenvalues, which can help to generally describe the system dynamics for any initial conditions in this regime. One of the applications is in atom microscopy. We propose a scheme to measure the distance between two atoms/molecules beyond diffraction limit. It covers the whole range from half the wavelength to sub-nanometers, utilizing both the atom localization technique and the collective frequency shift effect due to the cooperative effect in the radiation of the two atoms. Another application that we propose is to generate Coherent XUV radiation using Raman-type superradaince. We prove that intense short pulses of XUV radiation can be produced by Raman type superradiance from an ensemble of atoms/ions driven by visible or IR laser pulses.

Available in PDF, EPUB and Kindle. Book excerpt: Infrared and Millimeter Waves, Volume 1: Sources of Radiation explores modern sources of radiation available for use in the far-infrared and near-millimeter wavelength range of the spectrum. This book describes the operating principles and comparative performances of all three types of device: electron tubes, solid state devices, and optically pumped lasers. This volume is comprised of seven chapters; the first of which reviews the developments in the design and construction of high-power, high-efficiency millimeter sources and in the nonlinear theory for cyclotron masers. The second chapter deals with IMPATT devices for millimeter-wave power generation, with emphasis on device physics design considerations as well as cw and pulsed operations of IMPATT oscillators and amplifiers at millimeter frequencies. The chapters that follow focus on optically pumped lasers, backward wave oscillators, the Ledatron, and infrared and submillimeter-wave waveguides. This book concludes with a discussion on free electron lasers based on stimulated scattering from relativistic electron beams. An original reformulation of stimulated scattering theory that attempts to encompass all previous treatments is described and compared with available experimental data. This text also presents a semi-qualitative analysis of nonlinear saturation. This book will appeal to scientists and professional engineers.

This book was released on 2013-03-08 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1970s, researchers in Canada, the Soviet Union and the United States discovered that powerful infrared laser pulses are capable of dissociating mole cules such as SiF4 and SF6' This result, which was so unexpected that for some time the phenomenon of multiple-photon dissociation was not recognized in many cir cumstances in which we now know that it occurs, was first publicized at a time when the possibility of using lasers for the separation of isotopes had attracted much attention in the scientific community. From the mid-1970s to the early 1980s, hun dreds of experimental papers were published describing the multiple-photon absorp tion of C02 laser pulses in nearly every simple molecule with an absorption band in the 9 - 11 jJm region. Despite this impressive volume of experimental results, and despite the efforts of numerous theorists, there is no agreement among re searchers in the field on many fundamental aspects of the absorption of infrared laser light by polyatomic molecules. This book is devoted to reviells of the experimental and theoretical research that provides the foundations for our current understanding of molecular multiple photon exc itat i on, and to rev i ews of research that is pert i nent to the 1 aser sep aration of isotopes.

This book was released on 2011 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The Fourth International Conference on Laser Spectroscopy (FICOLS) was held in the Hotel Oberfahrt in Rottach-Egern, Tegernsee, June 11-15, 1979. Rottach-Egern is a well-known health resort situated on the southern end of Lake Tegernsee. As with the previous laser spectroscopy conferences in Vail, Megeve, and Jackson, the purpose of FICOLS was to provide ~n informal setting where an international group of scientists active in laser spectroscopy could discuss current problems and developments in the field. The program consisted essen tially of invited lectures with appropriate time provided for the latest postdeadline results. The conference was attended by 340 scientists representing 25 countries: Austria, Australia, Brazil, Canada,- Peoples Re public of China, Denmark, Finland, France, Germany (FRG), Germany (GDR), Great Britain, India, Italy, Japan, Nether lands, New Zealand, Norway, Pakistan, Poland, Spain, Sweden, Switzerland, U.S.k,, U.S.S.R., and Yugoslavia. Unfortunately five of our colleagues from Japan who planned to attend the meeting could not come due to an interruption of airline schedules, Their absence was a distinct loss to the conference. However, their papers will be published in one of the forthcoming issues of the journal Applied Physics. Numerous people have contributed to making the conference a success. Especially we would like to thank the members of the steering committee for their advice concerning the program.

Available in PDF, EPUB and Kindle. Book excerpt: This anthology is devoted to the theoretical and experimental study of coherent phenomena in quantum optics. Considerable attention is devoted to the investigation of cooperative effects in multilevel molecular and atomic systems. The theoretical analysis is based on a single approach, using the theory of groups, which makes it possible to present the results in a compact and physically elegant form. The results of a detailed experimental and theoretical investigation of the photon echo, self-induced transparency, and nutation are presented. The theory of a coherent resonant mechanism for the interaction of laser radiation with multi atomic molecules which causes "prompt" dissociation is presented. A number of applied pos sibilities, in particular, the control of radiation by laser light and laser isotope separation, are analyzed.

This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past half century has seen an extraordinary growth in the fields of cellular and molecular biology. From simple morphologi cal concepts of cells as the essential units of living matter there has been an ever-sharper focus on functional organization of living systems, with emphasis on molecular dynamics. Thus, life forms have come to be defined increasingly in terms of metabolism, growth, reproduction and responses to environmental perturbations. Since these properties occur in varying degrees in systems below the level of cellular organization, there has been a blurring of older models that restricted the concepts of life to cellular systems. At the same time, a search has begun for elemental as pects of molecular and atomic behavior that might better define properties common to all life forms. This search has led to an examination of nonlinear behavior in biological macromolecules, whether in response to electrical or chemical stimulation, for example, or as a means of signaling along a molecular chain, or as a means of energy transfer. Experimental knowledge in this area has grown rapidly in the past decade, and in some respects has outstripped theoretical models adequate to ex plain these new observations. Nevertheless, it can be claimed that there is now an impressive body of experiments implicating non linear, nonequilibrium processes as fundamental steps in sequential operations of biological systems.

Available in PDF, EPUB and Kindle. Book excerpt: The Seventh Rochester Conference on Coherence and Quantum Optics was held on the campus of the University of Rochester during the four-day period June 7 - 10, 1996. More than 280 scientists from 33 countries participated. This book contains the Proceedings of the meeting. This Conference differed from the previous six in the series in having only a limited number of oral presentations, in order to avoid too many parallel sessions. Another new feature was the introduction of tutorial lectures. Most contributed papers were presented in poster sessions. The Conference was sponsored by the American Physical Society, by the Optical Society of America, by the International Union of Pure and Applied Physics and by the University of Rochester. We wish to express our appreciation to these organizations for their support and we especially extend our thanks to the International Union of Pure and Applied Physics for providing financial assistance to a number of speakers from Third World countries, to enable them to take part in the meeting.
