Book Description
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.

Book Description
A tutorial discussion of the physical basis of atomic frequency standards is given.These principles are then related to the conditions under which an atom can be used as the working substance of a stable and accurate frequency standard.The three primary examples of atomic frequency standards--the hydrogen maser, the cesium beam, and the rubidium gas cell--are then discussed in terms of these principles and conditions.The functions of the fundamental parts of each device become apparent through this development.(Author).

Book Description
This volume covers advances in atomic frequency standards (atomic clocks) from the last several decades. It explains the use of techniques, such as laser optical pumping, coherent population trapping, laser cooling, and electromagnetic and optical trapping, in the implementation of classical microwave and optical atomic frequency standards. The authors describe the basic physics behind the operation of atomic clocks, explore new frequency standards that provide better stability and accuracy than conventional standards, and illustrate the application of atomic clocks in various areas.

Book Description
Of all measurement units, frequency is the one that may be determined with the highest degree of accuracy. It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency. This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards from atomic clocks, to frequency stabilised lasers. The whole is rounded of with a discussion of topical applications in engineering, telecommunications, and metrology.

Book Description
The Symposium on Frequency Standards and Metrology is an event held approximately every seven years, and is regarded as the premier conference in the field of advanced clocks and oscillators together with their applications in science and metrology. This series began with the first meeting at Universiteacute; Laval, Quebec Canada in 1971, and the last one was held in 2001 at the University of St. Andrews, Scotland. The 7th Symposium on Frequency Standards and Metrology is scheduled for October 5ndash;11, 2008 at the Asilomar Conference Grounds in Pacific Grove, California, USA. The Symposium is intended as a forum for bringing together international scientists and technologists engaged in the development of precise frequency standards and clocks, the study of their underlying physics, and their applications in metrology and tests of fundamental laws. The symposium has been traditionally held in a venue that promotes exchange of information on emerging ideas and latest achievements in the field, with a single-session approach which includes oral presentations by invitation, poster session(s) and keynote talks from internationally-recognized speakers. The program also includes social and other events aimed at promoting the exchange of technical and scientific information.
