Optical frequency comb generation dynamics. In (a) we report the laser cavity detuning, while in (b) the intra-cavity energy of the FF (blue) and SH (red) fields. In the bottom part of the figure, we report the snapshots for different spectral (c,e,g,i) and temporal (d, f, h, j) OFC regimes: (c, d) OPO, (e, f) modulation instability, (g, h) chaos and (i, j) a FF CS coupled to a SH dispersive wave.
