TL;DR: In this paper, the authors present a detailed theoretical and experimental investigation of the nonlinear dynamics of a semiconductor laser with optical feedback, showing that the coherence collapsed state is a chaotic attractor and that chaos is reached for increasing feedback level through a quasi-periodic route interrupted by frequency locking.

TL;DR: Theoretical results on wave mixing in traveling-wave semiconductor laser amplifiers are presented in this article, where the authors derive equations capable of treating the range from nearly degenerate to highly nondegenerate four-wave mixing.

TL;DR: The first experimental observation of the route to chaos for semiconductor lasers with weak optical feedback is reported, and the occurrence of quantum-noise-induced transitions between two attractors with different relaxation oscillation frequencies is demonstrated.

TL;DR: In this article, Carrier heating and spectral hole burning are shown to have a strong influence on the amplification of ultrashort pulses using semiconductor laser amplifiers, and approximate analytical expressions for the effective saturation energy in different pulsewidth regimes are derived.

TL;DR: In this article, the authors analyzed four-wave mixing processes in bulk semiconductor optical amplifiers by comparing experimental data at detuning frequencies up to 3 THz with numerical calculations based on semiclassical density-matrix equations.
