Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify chemicals and ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant black holes clearly, multiple radio telescopes must ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

Optical frequency combs are coherent light sources whose spectra consist of equally spaced lines, providing a ruler in the frequency domain. Semiconductor lasers have emerged as versatile platforms ...

The trick to creating a better quantum sensor? Just give it a little squeeze. For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing ...

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 ...

The challenges of terahertz-band components and frequency measurement. How a sophisticated combination of optical and electronic components representing advanced principles are being used to measure ...

Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has developed ...

Very-long baseline interferometry (VLBI) is a technique in radio astronomy whereby multiple radio telescopes cooperate to bundle their received data and in effect create a much larger singular radio ...

The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...
