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.

Cooperative Effects in Optics, Superradiance and Phase Transitions available in PDF, EPUB and Kindle. 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.

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.
