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

A review of ultrafast optics and optoelectronics
TL;DR: Apart from the generation of short pulses, this work will also address their detection and characterization, their modulation, and transmission effects, carrying the functionality of optoelectronics from a temporal resolution of a few picoseconds well into the femtosecond range.

Laser mode locking with addition of nonlinear index
Hermann A. Haus,Yaron Silberberg +1 more
TL;DR: In this paper, a nonlinear index medium introduced into a passively or actively mode-locked system can lead to shorter pulses and the authors suggest that active mode locking of Nd YAG lasers could be improved by such means.

TL;DR: In this paper, the first study of laser-tissue interaction in the femtosecond time regime was performed in chinchilla grey rabbits, where exposure to single laser pulses of 80 fs duration at 625 nm was performed.

The role of cavity dispersion in CW mode-locked dye lasers
TL;DR: In this article, the authors evaluated the contribution of a few components of a mode-locked dye laser cavity to the dispersion of pulses of about 100 fs or shorter and found that the dispersive contributions should influence the mode-locking behavior for pulses of up to 100 fs.

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.
