Complex pulse evolutions have been observed in a passively mode-locked CPM ring dye laser which have been shown to be highly sensitive to the frequency chirping processes in the laser cavity. For particular values of intracavity group velocity dispersion, the pulse evolutions are periodic and reminiscent of soliton evolutions. A numerical model of the laser is presented which successfully simulates the qualitative features of the real laser output temporally and spectrally. A careful investigation of the numerical model shows that, in the case of strong mode locking, the observed periodic pulse evolutions are not soliton-like, but result from a combination of frequency chirp and spectral walkoff. A distinct regime has been identified where soliton-like pulse evolutions are sustained, and the transition between the two modes of operation is related to the strength of the mode locking.
