Microfabricated Atomic Clocks at Nist
This paper presents the latest progress in the development, fabrication, and characterization of microfabricated atomic frequency references at NIST. With volumes below 10 mm the physics packages contain the complete integrated assembly for probing the ground-state hyperfine splitting frequency of the alkali atoms by coherent population trapping (CPT). This technique allows for a simple and com...
متن کاملChip - Scale Atomic Clocks at NIST
We describe recent efforts to develop microfabricated atomic frequency references capable of supporting a wide variety of commercial and military systems such as global positioning and wireless communication. These devices are anticipated to eventually have a volume of 1 cm, dissipate less than 30 mW of electrical power and maintain a fractional frequency stability better than 10 over one hour....
متن کاملDouble-resonance spectroscopy in Rubidium vapour-cells for high performance and miniature atomic clocks
We report our studies on using microwave-optical double-resonance (DR) spectroscopy for a high-performance Rb vapour-cell atomic clock in view of future industrial applications. The clock physics package is very compact with a total volume of only 0.8 dm. It contains a recently in-house developed magnetron-type cavity and a Rb vapour cell. A homedmade frequency-stabilized laser system with an i...
متن کاملReliability characteristics of microfabricated Rb mini-lamps for optical pumping in miniature atomic clocks and magnetometers
With the rising need for microfabricated chip-scale atomic clocks to enable high precision timekeeping in portable applications, there has been active interest in developing miniature (<few cm), chip-scale alkali vapor lamps, since vapor plasma discharge sources are currently the standard for optical pumping in double-resonance clocks. We reported in 2012 a first microfabricated chip-scale Rubi...
متن کاملAtomic vapor cells for chip-scale atomic clocks with improved long-term frequency stability.
A novel technique for microfabricating alkali atom vapor cells is described in which alkali atoms are evaporated into a micromachined cell cavity through a glass nozzle. A cell of interior volume 1 mm3, containing 87Rb and a buffer gas, was made in this way and integrated into an atomic clock based on coherent population trapping. A fractional frequency instability of 6 x 10(-12) at 1000 s of i...
