Multiple-Pulse Operation and Bound States of Solitons in Passive Mode-Locked Fiber Lasers
Figure 15
Spectra of ultrashort pulse described by (8). (a) Spectral profiles of established solitons with different chirps: (1) , (2) , (3) , (4) . (b) Variation of the chirp on the plane of the nonlinear-dispersion parameters (). For the dashed line , for the solid curves , the arrows point the directions of maximal increase in the chirp . The spectral profiles in the figure (b) demonstrate typical spectra for the three areas separated from each other by the solid curves.
