This unique new level of control of atomic motion allows researchers to study the behavior of atoms and quantum mechanical properties. Different atomic cooling techniques exist, e.g. Doppler cooling, Sub–Doppler […] the first-order Doppler shift vanishes. Laser cooling re- duces substantially the second-order Doppler shift (rela- tivistic time dilation). Inaccuracies of atomic clocks based on stored ions may eventually be less than 1 part in 1018 (Ref. 4).

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.
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.

Cooling atoms is equivalent to slowing them down, which makes them a lot easier to study.

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. today’s clocks of this kind are summarized in section 5.
