Now a Japanese company has commercialized one approach—an optical-lattice clock it claims is the most accurate on the market.

A proposed experiment that would involve trapping atoms on a two-layered laser grid could be used to study the mechanism ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber ...

The invention – called the optical lattice clock – is a thousand times more accurate than cesium atomic clocks used for international timekeeping and is a contender for redefining how long a ...

According to the Kyoto-based company, its compact optical lattice timepiece, released on March 5, is a kind of strontium atom clock. Using a specialized laser beam called the “magic wavelength ...

There is a clock called the "optical lattice clock." First, each atom cooled by laser is captured in a 3-D micro space (optical lattice), which is created by interference of laser beams with special ...

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

I would have guessed two meters high from photo. The boxes in the middle with the controls must be very small, much smaller than audio equipment, for example. If I bought one, I'd have the world's ...

Without Katori's custom-made timekeeper, the experiment wouldn't have been possible, as conventional optical lattice clocks are so mammoth in size that just one can fill an entire laboratory.
