Optical manipulation involves laser cooling and trapping of atoms, reducing their kinetic energy to extremely low temperatures. This process allows scientists to create ultracold atomic ensembles with minimal thermal motion, leading to narrow linewidths in atomic transitions. Narrow linewidths are essential for achieving high precision in atomic clocks. Laser cooling and optical manipulation can also extend the coherence time of atomic states, reducing the sensitivity of atomic clocks to external disturbances. Longer coherence times translate into increased clock stability, allowing atomic clocks to maintain their precision over longer intervals.
