The chapter reviews the physical foundations, the theoretical analysis, the experimental implementation, and possible applications of the three main regimes of ultrafast pulse generation by semiconductor lasers (SLs): gain-switching, passive Q-switching (QS) or self-sustained pulsation (SSP), and mode-locking. Key parameters governing the laser performance, and advantages and limitations of these three methods of pulse generation are discussed. Emphasis is given to the recent progress in theory and experiment, harnessing new materials and physical principles, and current application trends.
