Multiple-Pulse Operation and Bound States of Solitons in Passive Mode-Locked Fiber Lasers
Figure 12
Temporal and spectral distributions of intensity of the two-soliton molecule (a), (d) for the ground steady state (minimal distance between solitons), (b), (e) for the first excited steady state, and (c), (f) for the second excited steady state. All steady states are stable. The laser parameters are the same as in the case of Figure 10.
