FIGURE 1. Top: An OFC generated by a modelocked laser. Bottom: A periodic pulse train in the time domain corresponds to a series of discrete frequencies in the frequency domain. The frequency comb is shifted in frequency space by a carrier-envelope offset frequency fceo, which arises from the carrier envelope phase slip Δφ between successive pulses. Apart from this offset, the comb consists of equally spaced spectral lines separated by the repetition rate frep.
