Abstract

An optically pumped primary frequency standard is being constructed at the National Institute for Science and Technology. To achieve the potential accuracy of this new technology a thorough reconsideration of all the potential systematic errors has been undertaken. Based on the needs of the optical pumping process and other improved technologies (ovens and cavities), a unique beam tube has been designed and fabricated. The laser performance necessary to allow full realization of the optically pumped clock’s potential has been achieved by an optical feedback technique. The design goal is a short term perfoRance of σy(τ) ≤ 5×10−13/√τ with a total frequency uncertainty of no more than 10−14
