For an atomic clock, it is the time of free flight of the atoms between the two microwave pulses used to probe the atomic transition.In an earth bound fountain clock, using laser cooling technology, the time of flight is limited by gravity to about half a second (the atoms fall).

Each clock also has two laser boxes. Box 1 includes three lasers, two for cooling and one for repumping. Box 2 encloses lasers for creating an optical lattice trap, further cooling, and exciting the atoms for timekeeping.

12 Sep 2019 Next-generation atomic clocks stabilize the color, or frequency, of a laser to atoms “ticking” between two energy levels. The tweezer clock traps

4). The main disadvantage of using stored ions in atomic While the photonic design for a chip-scale atomic clock 2 consists of only a vertical-cavity surface-emitting laser (VCSEL), lenses and filters, and a detector, more advanced clocks involving atom cooling require additional components that greatly increase the overall size and complexity, such as laser sources that can be frequency-tuned to different atomic transitions, amplitude modulators to transition. The lattice laser and clock laser have the same polarization direction and overlap onto the cold atomic cloud.

2018-07-24 · Laser cooling of atoms provides an approach to improve the performance of atomic clocks further 1, particularly in applications that require precision time-keeping over long time scales.

Using the technique of laser cooling, an improved type of caesium AFS has been developed during the last decade. The so-calledfountainclockshavematuredtobeoperatedregularly and to contribute to the realization of International Atomic Time (Parker et al 2001, Weyers et al 2001). Their properties 2016-09-13 2008-04-02 When flying through the resonator of an atomic clock, a laser-cooled atom thus is available for a much longer time and allows its resonant frequencies to be more measured precisely. If an atom or ion is stored in a trap, it can only perform a vibrational motion in a limited space.

Introduction In the microgravity environment of the Interna- tional Space Station (ISS), cesium atoms can be launched more slowly through the clock's microwave cavity than on Earth, reducing a number of effects Compact, laser-cooled atomic clocks.
