KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

Some of the X-ray radiation circulating in the cavity is allowed to escape downstream, providing a beam of monochromatic and coherent X-ray pulses. They have called their system X-ray Free-Electron ...

Nimra Shakoor and Charles R. Goulding take readers inside Columbia’s six-year experiment that turned quiche, pizza, and pie into a laser-cooked showcase of how 3D printing could redefine the future of ...

Argonne National Laboratory has made extremely precise measurements of unstable ruthenium nuclei. The measurements are a ...

Non-contact displacement sensors are increasingly being adopted across industries for their precision, reliability, and ...

For more than 50 years, phase-shifting interferometry has been the technology of choice for high-precision surface form ...

Icy weather can turn routine travel into a high-risk gamble. On roads, ice causes about 20% of weather-related car crashes ...

While it has become a word, laser used to be an acronym: “light amplification by stimulated emission of radiation”. But there is an even older technology called a maser, which is the ...

Optical atomic clocks are 100 times more precise than cesium clocks. Scientists are using them to search for dark matter and measure gravity.

UK researchers shrink atomic fountain clock to 5 percent size, keeping ultra-precise time and making it portable for wider ...

C.Carreau A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime ...
