Nobel Laureate and distinguished physicist Steven Chu discusses laser cooling. Atomic clocks based on caesium The role of optical clocks Laser cooling State prepare Probe clock transition Detect Steer frequency 17 ~ 1015 Hz Optical Laser cooling of atoms has opened up new possibilities in the field of atomic frequency standards. A Cesium atomic fountain, first proposed by Zacharias in 1953, is now feasible: the atoms, first cooled by six laser beams, are launched upward using laser light, pass once through a microwave cavity, continue their ballistic flight and then fall through the same cavity. Laser cooling methods to reach quantum degeneracy Laser cooling of atoms has not only supplied the basis for the control and manipulation of matter at the quantum limit, e.g. in form of Bose-Einstein condensation, but has also resulted in a number of important applications and devices, many of which are tied to precision measurements and atomic clocks. Laser cooling denotes a variety of techniques for reducing the temperature (i.e., the random motion) of small particles such as atoms or ions. In many cases, extremely low temperatures are achieved.

NIST's new atomic time interval standard, the NIST-F2, combines laser cooling with a liquid nitrogen-cooled chamber to achieve unprecedented accuracy in a ce Since 2004, more accurate atomic clocks first cool the atoms to near absolute zero temperature by slowing them with lasers and probing them in atomic fountains in a microwave-filled cavity. An example of this is the NIST-F1 atomic clock, one of the national primary time and frequency standards of … Laser cooling in diffuse light 4. Compact cold atom clock 5.

This is so accurate that it would not have gained or lost a second if the clock had started running at the dawn of the universe. Laser beams also apply a torque which, by changing the plasma angular momentum, changes the plasma density. Atomic clocks are an important application of ion trap plasmas.

Atomic clocks with laser-cooled atoms, so-called cold atom clocks, are now the most precise and accurate frequency standards, and are used in International Atomic Time (TAI). A typical cold atom clock on ground is the atomic fountain clock [6, 7]. Because of William Phillips’ work in laser cooling, atomic clocks are almost a thousand times better than they used to be. Two transportable optical atomic clocks carry spectroscopy chambers (black boxes) and supporting equipment. 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.
