For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be ...

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 ...

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 ...

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 ...

The atomic clocks that give extraordinary precision to the Global Positioning System (GPS) are based on transitions between energy states of atoms. Many advances have been made since the launch of the ...
