Frequency Comb characterization with High-Resolution Fourier Transform Spectroscopy (FTS)

– Explanation and applications of Frequency Combs – Frequency combs are very precise light sources which can be used for the measurement of absolute optical frequencies, so they can serve as an optical clockwork for precision spectroscopy, optical sensing, distance measurements, laser noise characterization, telecommunications, and in fundamental physics. The spectrum of an optical frequency comb consists of a train of equidistant lines, i.e. it has equidistant optical frequency components, while the intensity of the comb lines can vary substantially…
