Excitation dynamics of a dark soliton and SRS at different pump powers. (a) The integrated dispersion with an AMX based on equation (7), $D_{\mathrm{i}\mathrm{n}\mathrm{t}}(\mu ,8,3)$, for all cases. (b) The averaged intracavity power for cases (iv) (blue), (v) (green), (vi) (red) and detuning (black) as a function of time. (c) Spectral evolution of the intracavity fields (top), a representative spectrum (bottom), and temporal waveform (inset) for each case. The dark soliton exists for a shorter detuning range at a higher pump power (stages II and III). In other words, increasing pump power is not always beneficial in accessing a dark soliton state.
