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

The role of amplitude and phase shaping in the dispersive-pulse regime of a passively mode-locked dye laser
Mark Beck,Ian A. Walmsley +1 more
TL;DR: In this paper, a phenomenological numerical model was developed that accounts consistently for the finite bandwidth of the saturable gain and absorbing media for a sub-100-fs pulse generated by a colliding-pulse mode-locked dye laser.

Highly efficient widely tunable subpicosecond double mode-locked laser
Zafer A. Yasa,Nabil M. Amer +1 more
TL;DR: In this paper, a high average power (≈150 mW) subpicosecond (0.5 ps) passively double mode-locked dye laser is described and two synchronized cw pulse trains are generated which are independently tunable over broad wavelength ranges.

Femtosecond Probing of Photoinduced Refractive Index Changes in Semiconductors
Eric C. Fox,H. M. van Driel +1 more
TL;DR: It is envisioned that a gate optical pulse can be used to alter the local refractive index in a device and thus modify the direction of propagation, phase, or transmission of an optical pulse passing through the device in what is commonly referred to as light-by-light switching.

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.
