TLDR
In this article, a novel passive mode-locking technique was proposed in which two synchronized counterpropagating pulses interact in a thin, saturable absorber to produce a short pulse.Abstract:
We report a novel passive mode‐locking technique in which two synchronized counterpropagating pulses interact in a thin, saturable absorber to produce a short pulse. Continuous stable trains of pulses shorter than 0.1 psec are obtained using a ring laser configuration.read more

Femtosecond Multiphoton Photoelectron Emission from Metals
TL;DR: In this article, it has been shown that photo-electron emission from metals can be observed in the picosecond time regime, when the laser pulse durations are comparable to or shorter than the electron-phonon energy relaxation time.
Implementation and characterization of mode-locked fiber lasers
TL;DR: In this paper, the effects of the cavity settings on the characteristic of the laser have been studied, and it is found that pulse train with short pulse width can be obtained by modulating the lightwave with high modulation frequency, deep modulation depth and incorporating a wide bandwidth filter into the ring cavity.

Pulse evolution in mode-locked quasi-continuous lasers
TL;DR: In this article, a model of a passively mode-locked quasi-continuous laser is discussed and the evolution of pulses in various cavity configurations is traced and the combined action of amplifier and absorber saturation is shown to lead to rapid pulse compression even when the pulse duration is far shorter than the relaxation time.

Tunable distributed‐feedback dye laser
TL;DR: In this article, an efficient broadly tunable dye-laser action with a narrow line output has been demonstrated with a mirrorless laser system using distributed feedback, which was obtained from a spatial modulation of both gain and index of refraction induced by pumping a liquid organic dye solution with fringes formed by the interference of two coherent light beams.

Passive mode locking of the cw dye laser
TL;DR: In this article, a stable continuous output of picosecond pulses has been achieved using second-harmonic generation (SHG) measurements, and the pulses are transform limited and are wavelength tunable over the range 5900-6100 A.
