Production of picosecond and subpicosecond pulses with passively mode-locked dye lasers is investigated. Production of highly synchronous picosecond pulses at two wavelenths is demonstrated using the linear continuous wave double mode-locked dye laser. Previously measured wide cross correlations are explained by the presence of substructure in the pulses. In some cases this substructure is clearly resolved in the correlation measurements. The colliding pulse mode-locked ring dye laser is studied both experimentally and theoretically. The amplitude and roundtrip stability of this laser is quantified. The duration of the pulses produced is seen to be limited by both the cavity dispersion and the thickness of the saturable absorber medium used. The double mode-locking of the ring dye laser is investigated. Preliminary results show that the pulses produced are neither as compact nor as stable as initially expected. The mode-locking of the xenon-laser-pumped wind dye laser is proposed. A scheme for the reliable mode-locking of semiconductor lasers is also proposed. Ultrashort light pulses are already used in time resolved optical spectroscopy. They will be useful in the future for very high data rate optical communication systems.
