The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

An optical clock sets a record, edging us toward a new second
Physicists are quietly rewriting one of the most basic units in science, using a new generation of optical clocks that can ...
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference ...
