The research focus of this dissertation is the generation of stable pulse trains with extreme characteristics.

The presented pulse train signals posses self-organising dynamics. Such behaviour enhances signal stability and reliability, especially for critical laser system applications.

The new extreme wave signal dynamics is obtained using numerical simulations of the well-established complex Ginzburg-Landau equation (CQCGLE). The CQCGLE models highly nonlinear, non-stationary regimes applicable to laser operation.

This dissertation reveals extreme optical pulses in both the anomalous and the normal dispersion regimes. Notably, the discovery of spiny solitons offers new insight into the nature of dissipative systems.

These new extreme wave dissipative dynamics have essential applications to new and improved laser systems.
