A laser clock developed by DLR has achieved a record level of accuracy for optical clocks, with a deviation of just one second every 30 million years. Laser clocks are set to improve satellite ...

A matchbook-sized atomic clock 100 times smaller than its commercial predecessors has been created by researchers. The portable Chip Scale Atomic Clock -- only about 1.5 inches on a side and less than ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

It’s clock time again on Hackaday, this time with a lovely laser-cut biretrograde clock by [PaulH175] over on Instructables. If you’ve never heard of a ‘biretrograde clock,’ well, we hadn’t either.
