A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

JILA physicists have demonstrated a novel laser design based on synchronized emissions of light from the same type of atoms used in advanced atomic clocks. The laser could be stable enough to improve ...

JILA team has now built the super-radiant design based on strontium atoms that it first proposed four years ago. A team of researchers at a laboratory affiliated with the US National Institute of ...

Designing a unique clock to flex your technical skills can be a rewarding experience and result in an admirable showpiece for your home. [Andres Robam] saw an opportunity to make a laser-pointer clock ...

In a world deprived of stock hardware other than #6-32 bolts and sheets and sheets of acrylic, [Lawrence Kesteloot] took it upon himself to design and build a laser-cut pendulum clock. No Pricey CAD ...

Those wacky artists at Art Lebedev are at it again. This time, they’ve created a concept clock that uses a single laser beam directed by 60 rotating mirrors to tell us what time it is. The bad news is ...

We may soon be redefining what one second of time is, thanks to French scientists who have devised a new clock, called the optical lattice clock, that is so accurate, it only loses a second once every ...

We have seen a few of these recycled clocks here on Geeky Gadgets, made from various recycled parts from old PCs and Macs. This one is definitely one of the cooler ones. The Laser Etched Recycled ...

Researchers have proposed building a nuclear clock that would lose only one-tenth of a second over 14 billion years, the current age of the universe. The design would be 100 times more accurate than ...

Physicists have demonstrated a novel laser design based on synchronized emissions of light from the same type of atoms used in advanced atomic clocks. The laser could be stable enough to improve ...

Here’s an LED-lit keychain device that lets you project an image of the time of day. Curiously named a Laser Clock, there aren’t really any lasers involved, according to a nice guy we talked to at the ...
