Optical frequency comb

An optical frequency comb is a technology that produces a series of evenly spaced light frequencies, much like the teeth of a comb. It's generated by a laser and can be used to measure distances, detect gases, and improve precision in various scientific fields. The unique pattern of frequencies allows researchers to compare different wavelengths of light very accurately. This capability has led to advancements in areas like telecommunications, metrology, and spectroscopy, making it a powerful tool for scientists and engineers in exploring and understanding the properties of light and matter.
