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.

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 ...

Radio telescopes let you study the universe by collecting faint radio waves from distant objects. To see extremely small ...

Cambridge, MA – 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 ...

For the first time ever, scientists have used a technique called "quantum squeezing" to improve the gas sensing performance of devices known as optical frequency comb lasers. These ultra-precise ...

Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...

Researchers at the University of Colorado Boulder have improved the gas sensing capabilities of optical frequency comb lasers by implementing a technique called "quantum squeezing." These highly ...

Researchers have shown that dissipative Kerr solitons (DKSs) can be used to create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical ...

The search for rocky, Earth-like exoplanets has received a boost, with the arrival of a new laser frequency comb at the European Southern Observatory’s La Silla Observatory in Chile. Built by a team ...

Ultrabroadband IR frequency comb could be used for detection in portable spectrometers. The comb uses a double-chirped mirror. Researchers at MIT have demonstrated a compact, fully integrated ...

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 ...
