The end of the era of quartz frequency standards began in 1949 with the development at NBS of the world's first atomic frequency standard based on an ammonia absorption line at 23.87 GHz (5).
The development of atomic frequency standards at NIST is discussed and three of the key frequency-standard technologies of the current era are described.
In describing work on the three classes of atomic frequency standards, emphasis is placed on the most recent devices and the results achieved with them.
Several general aspects of the various types of atomic frequency standards, including atomic-state interrogation time, the form of the microwave cavity, and linecenter servomechanisms are briefly discussed next.
The basic concepts upon which atomic frequency standards are based were developed in the early 1940s by Rabi (10), but Ramsey contributed a major improvement with his method of successive oscillatory fields" (11).
Though it was agreed that the improvement of other atomic frequency standards, using for example hydrogen or thallium atoms, ought to be pursued actively, the Comite Consultatif pour la Definition de la Seconde, at its meeting of 12-13 July 1967, recommended unanimously to the Comite International des Poids et Mesures not to wait any longer ..."

NIST has achieved a technical milestone in its push to develop optical atomic frequency standards and clocks.
Such a crystal, confined in a Penning trap with its rotation locked to a rotating electric field, has potential applications in atomic frequency standards and quantum logic.
