Cooling of atom clouds and single ions by laser irradiation to temperatures close to zero kelvin has considerably advanced the development of atomic clocks and frequency standards. This chapter briefly summarizes first the method to characterize the quality of frequency standards by the Allan standard deviation.

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). Ideally, we'd like an atomic clock to be cooled to as near to absolute zero as possible. Simply sticking the atoms into a super-powerful refrigerator won't work, however. The gas containing the atoms would condense on the walls of the refrigerating container, and for atomic clocks, that's no good. 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.

and that's what laser cooling could be used for. och det är vad laserkylning kan användas för. 00:04:23. The other thing would be, I would think atomic clocks,.

In addition to clocks and navigation, they’re ideal for quantum computers and for linking them into quantum networks. That’s part of what inspired the NIST researchers to find laser-cooling Atomic Clocks/Atom Cooling. Single frequent laser radiation, precisely balanced in narrow linewidth and tunability, will excite, detect or manipulate atoms in spectroscopy, such as Rubidium, Cesium, Potassium, Calcium, Lithium, Strontium and others.

The Laser Cooling That Makes Atomic Clocks So Accurate 21 June, 2010 Nobel-Prize winning physicist William Phillips admits that "laser cooling" is a somewhat confusing concept.

The single-laser simplified version of the Yb optical clock would use only the 556 nm laser for all functions: stimulated slowing of the Yb beam, cooling and trapping in the MOT and also for the “clock Two Pune Research Institutes Are Building India’s First Optical Atomic Clocks. The clocks will only skip one second in more than 13.8 billion years, which is the approximate age of our universe. Atomic clocks are the most accurate timepiece you can own. Because of the way they operate and how well they run, you can depend on their precision. You rarely have to set them yourself. When the clocks are changed during the fall and sprin Atomic clocks are the most accurate timekeepers in the world.

2016-09-13 · Both traps are cooled with a continuous wave 167 nm laser. The expected clock laser stability can reach $9.0\times10^{-17}/\sqrt{\tau}$. For the second trap, in addition to 167 nm laser Doppler cooling, a second stage pulsed 234 nm two-photon cooling laser is utilized to further improve the accuracy of the clock laser.
