Pulse instabilities in harmonic active mode-locking: a time-delayed approach
Elias R. Koch, Svetlana V. Gurevich, Julien Javaloyes
We propose a time-delayed model for the study of active mode-locking that is valid for large values of the round-trip gain and losses. It allows us to access the typical regimes en…
Aberration-driven tilted emission in degenerate cavities
