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

Correction of beam break-up in self-mode-locked Ti:sapphire lasers
TL;DR: In this paper, the effects of the thermal aberration due to laser pumping on the beam shape and on the initiation of the self-mode-locked regime were analyzed and it was shown that such an aberration produces the break up of the beam profile when the laser is operated near the edges of the geometrical stability zones.

Gratings in Laser Devices and Experiments
TL;DR: In this paper, some dynamic grating effects are discussed, which are relevant to lasers and other optical devices and experiments, and it is expected that dynamic gratings will be increasingly used in future photonic systems and quantum electronics extending the range of applications described in the following.

Mutual dynamics between synchronous solitons in a bidirectional mode-locked fiber laser.
TL;DR: In this paper, the mutual dynamics between synchronous solitons in a bidirectional mode-locked fiber laser are studied via dispersive Fourier transform methodology, indicating the low and high mutual linear dependences of the spectral energy jitters in stable and breathing mode-locking states, respectively.

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.
