(color online) Existence region of a single dark pulse (gray) in the (α, F) parameter space. The inset exhibits some typical, single dark-pulse-related field intensity profiles and their comb spectra. The blue and red curves determine the pump boundaries of dark pulse generation. For the two curves, the functional relation between and α is given by Eq. (5).
