Atomic frequency standards provide the most accurate measurements in physics. The Quantum Physics of Atomic Frequency Standards is an extensive survey of the subject covering both theoretical and experimental aspects together with applications. As an accessible and essential reference it will be invaluable to experienced researchers and beginners alike. The first volume begins with a quantum mechanics treatment of the interaction of static fields and electromagnetic radiation with atoms and molecules. Each of the important phenomena - noise, relaxation, broadening and frequency shifts - is treated in detail and optical pumping and population inversion are explained. With all the background material now in place the major part of these volumes is devoted to a theoretical analysis of the operation of the numerous atomic frequency standards that are either in use, are being studied or have been proposed. * Caesium atomic beam frequency standards * Hydrogen maser * Rubidium frequency standards * Mercury ion trap * Frequency stabilized lasers In the final chapter the authors discuss the impact of atomic frequency standards on navigation and communication systems, in industry, in new technology and on fundamental research.Reseña del editor:
Atomic frequency standards are very stable and accurate frequency sources. They are now used, for example, in high-speed communication, in navigation systems and in time-keeping. This study, which examines present knowledge regarding the operation of such devices, is designed to be used by the newcomer to the field as well as by the experienced researcher. The text describes some applications of quantum electronics including experimental methods, fresh approaches to physical theory and techniques of calculation which workers in other fields may find can be transposed to their own. For readers who wish to explore the field more deeply, all the appropriate mathematical derivations are given in appendices and there is an extensive reference list.
