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

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.
