Optical lattice clock

Wikipedia Overview

In atomic, molecular, and optical (AMO) physics, an optical lattice clock is a type of atomic clock that uses neutral atoms confined in an optical lattice, which is a periodic array of laser light, as its timekeeping reference. In these clocks, strontium (Sr) or ytterbium (Yb) atoms are cooled to nearly absolute zero and held in place by intersecting laser beams forming a stable 'egg-crate' pattern of light. The atoms' ultra-narrow optical frequency transitions work as the clock's ticking signal, with frequencies of hundreds of trillions per second, vastly higher than the microwave frequencies used in conventional cesium atomic clocks. This higher frequency allows optical lattice clocks to divide time into much finer intervals. By probing thousands of trapped atoms simultaneously and averaging their synchronised oscillations, optical lattice clocks achieve extraordinary stability and accuracy. Due to their accuracy, they are considered prime candidates for a future redefinition of the second in the International System of Units (SI). For example, a cesium clock might drift by a second in about 30 million years, whereas a strontium optical lattice clock would drift only about one second over 30 billion years.
