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
This work reviews the principles underlying quantum-based atomic clocks, with introductory chapters placing them in context with the development of mechanical clocks and electronic quartz-controlled clocks. The book details design principles of the rubidium, cesium, hydrogen maser, and mercury ion standards; changes enabled by the advent of the laser; and the time-based global navigation systems, Loran-C and the Global Positioning System. The new edition includes such recent developments as clocks based on quantum resonance at optical frequency in individual ions confined in miniature electromagnetic traps. The Quantum Beat explores the subject with a minimum of mathematical formalism.
