Transmitting extremely precise clock signals over long distances could help pave the way to a new definition of the second Atomic clocks based on the oscillations of a cesium atom keep amazingly steady time and also define the precise length of a second. But cesium clocks are no longer the most accurate. That title has been transferred to an optical clock housed at the U.S. National Institute of Standards and Technology (NIST) in Boulder, Colo. that can keep time to within 1 second in 3.7...
In future, optical fibers could connect all optical atomic clocks within Europe – a milestone for various users of optical frequencies in research and industry Optical atomic clocks measure time with unprecedented accuracy. However, it is the ability to compare clocks with one another that makes them applicable for high-precision tests in fundamental theory, from cosmology all the way to quantum physics. A clock comparison, i.e. a comparison of their optical frequencies, proved to be...
When people think of space technologies, many think of high-tech solar panels, complex and powerful propulsion systems or sophisticated, electronic guidance systems. Another critical piece of spaceflight technology, however, is an ultra stable, highly accurate device for timing - essential to NASA's success on deep-space exploration missions. NASA is preparing to fly a Deep Space Atomic Clock, or DSAC, demonstration that will revolutionize the way we conduct deep-space navigation by...
[ Watch the Video ] 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. This type of laser could boost the performance of the most advanced atomic clocks and related technologies, such as communications and navigation systems as well as space-based astronomical instruments. Described in the April 5, 2012, issue of Nature,* the JILA laser prototype relies on a...
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. To be published in the journal Physical Review Letters, the research provides the blueprint for a nuclear clock that would get its extreme accuracy from the nucleus of a single thorium ion. Such a clock could be useful for certain forms of secure communication – and perhaps of greater...
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. In early time, the sun or grains of sand in an hourglass kept time. Over the years technology allowed for clocks you could wind, watches with quartz oscillators, and more recently the atomic clock. The atomic clock uses an electronic transition frequency to keep time. Considered quite accurate, atomic...
