This makes it possible for two mirrors with light between them to register their oscillations. "In traditional atomic clocks, the detection heats up the atoms, requiring atoms to be freshly loaded ...

They trapped thousands of strontium atoms vertically in grids of laser light. Atomic clocks rely on the steady frequency at ...

Next, researchers examined timing data from microwave atomic clocks aboard GPS satellites ... on electron-mass variations ...

Scientists have designed a new atomic clock, using laser light and ytterbium atoms, that is ten times more stable than previously reported clocks. Ytterbium atoms are generated in an oven (large ...

The ultimate accessory in exact timekeeping — the atomic clock — is set to become even more precise, after ultrashort laser pulses were successfully transmitted across open air to help ...

When atomic clocks first appeared in the 1960s, they defined the second based on the properties of cesium atoms, which absorb and emit light at a reliable frequency. These cesium-based atomic ...

The length of a second hasn't been updated in 70 years. That may change soon. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...

Since the 1960s, the second has been defined by atomic clocks made of cesium atoms, which absorb and emit light at a particular frequency that determines the length of a second. But “there have ...

BACON and other projects are tinkering with a much newer type of atomic clocks, called optical clocks, which rely on light. Because light has higher frequencies than microwaves, and thus shorter ...

Up front: Atomic clocks have been in popular use since the ... With the optical technique, the researchers are essentially measuring light-emitting atomic transitions as opposed to those that ...

This is for superior chip size atomic clocks. The U.S. has superior in lab and large atomic and laser clocks. They are shrinking them down and making them cheaper. Hundreds of bucks instead of ...

But in the next decade or so, that could change: Ultraprecise atomic optical clocks that rely on visible light are on track to set the new definition of a second. These newer versions of the ...
