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 ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

…and Stanford launches “micro” frequency comb, as basis for mass-market adoption of such devices. An ultraviolet photon-counting dual-comb spectrometer. Scientists in the group of Nathalie Picqué at ...

NTT Corp. (NTT) and Tokyo Denki University, both based in Japan, have succeeded in further stabilizing the output of an optical frequency ruler generated by modulating the intensity and phase of laser ...
