Latest Atomic clock Stories
Atomic clocks based on the oscillations of a cesium atom keep amazingly steady time and also define the precise length of a second.
In future, optical fibers could connect all optical atomic clocks within Europe – a milestone for various users of optical frequencies in research and industry
When people think of space technologies, many think of high-tech solar panels, complex and powerful propulsion systems or sophisticated, electronic guidance systems.
Physicists at JILA have demonstrated a novel “superradiant” laser design, which has the potential to be 100 to 1,000 times more stable than the best conventional visible lasers.
A clock accurate to within a tenth of a second over 14 billion years – the age of the universe – is the goal of research being reported this week by scientists from three different institutions.
As time passes, new technology evolves in order to keep time. Soon the trusty atomic clock may be replaced by a nuclear clock, which keeps time to 1/20th of a second in 14 billion years.
Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength.
