Frequency combs are specialized lasers that generate evenly spaced-out lines of light akin to the teeth of a comb or, more aptly, the tick marks on a ruler. In the roughly quarter-century of their ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

(Nanowerk News) Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its hundreds of evenly spaced, ...

Stanford researchers have unveiled a new type of frequency comb, a high-precision measurement device, that is innovatively small, ultra-energy efficient, and exceptionally accurate. With continued ...
