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 ...

The research is published in Light: Science and Applications (Nature).

This requires a precise source of terahertz waves, in addition to a sensitive detector, and the terahertz frequency comb is ideal for making such measurements in the lab.

Optical frequency combs emit a continuous train of short, closely spaced pulses of light containing millions of colors, which can be used to measure light waves as if they were radio waves.

By using a laser that produces long wave infrared radiation, such as a quantum cascade laser, they can use frequency combs for high-resolution sensing and spectroscopy.
