Optical frequency combs

Optical frequency combs are unique tools in science and technology that consist of a series of evenly spaced light frequencies, like the teeth of a comb. They are created by lasers and can be used to measure distances very precisely, improve telecommunications, and conduct high-precision spectroscopy. Each "tooth" of the comb represents a specific frequency of light, allowing researchers to analyze materials and gases with exceptional accuracy. Their ability to provide precise measurements makes them invaluable in various fields, including metrology, astronomy, and even medical diagnostics.
