Laser frequency comb filters let only evenly spaced, sharply defined frequencies of light pass through. The uniformly spaced frequencies resemble the teeth of a comb, hence the name. They’re used to ...

A frequency comb is a special kind of laser light whose spectrum, or set of frequencies, resembles the teeth of a comb. Instead of containing just one colour (one frequency), it emits a large number ...

Laser frequency combs are valuable analytical tools for observing chemical phenomena or detecting the presence of particular species at low concentrations. The key to these applications is the ...
