Optical Frequency Combs: A Ruler for Light
2025-01-30
Optical frequency combs, Nobel Prize-winning technology, act like a ruler for light, precisely measuring the frequencies of light waves across the electromagnetic spectrum. This revolutionary technology bridges the gap between radio/microwave and optical frequencies, enabling advancements in atomic clocks, astronomy, atmospheric science, and even medical diagnostics. NIST scientists are at the forefront of this field, continuously improving the accuracy and miniaturization of these devices. Future applications include integration into microchips for broader commercial use.
