Optical frequency combs are lasers that can act like rulers to measure specific frequencies of light with high accuracy. Scientists can use them to detect and identify chemicals and pollutants ...

As long as we can use our platform to measure the dispersion, we can design and fabricate a DCM that compensates for it," Hu ...

Optical frequency combs, as a time and frequency "ruler," have important applications in precision ranging. Conventional dual ...

But don’t let its size fool you. This tiny laser could power the next generation of self-driving cars, space science tools, and high-precision clocks.

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 ...

A powerful new laser could soon reshape how we measure, communicate, and detect gases. This invention promises to make ...

A team of researchers have found breakthrough technology that instantly identifies chemicals using a portable chip-based laser device.

The breakthrough came from probing thorium-229 nuclei with a laser device called a frequency comb. The set-up isn’t technically a clock, because it hasn’t been used to measure time.

Researchers demonstrated a broadband infrared frequency comb that can operate stably, efficiently, and accurately without the need for bulky external components. The device could be utilized in a ...
