Atomic clocks use the oscillations of atoms as timekeeping ... laser-cooled and trapped into a lattice formed by laser beams. He found that the laser tuned to a certain wavelength would be ...

A standard atomic clock takes a beam of atoms that are in two states and uses a magnetic field to remove all the atoms in one state. The remaining atoms are subjected to a microwave signal which ...

The atomic clock on China's space station is currently ... a mobile command centre then issues attack commands to the vehicles. The microwave beams can achieve a power-combining effect of "1+1>2 ...
