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

Chapter 7 Photoemissive Probing
A.M. Weiner,R.B. Marcus +1 more
TL;DR: In this paper, the concept of photoemissive probing is discussed, and the authors present an optical system for generating and focusing light pulses onto the device under test (DUT), a means of generating a drive signal and synchronizing this signal with the probe pulses, a vacuum chamber, an electron energy analyzer and spectrometer, and instrumentation for data processing.

Measurement of 50-fs (rms) Electron Pulses
TL;DR: In this paper, a frequency-resolved autocorrelation method was proposed to determine the bunch length by using coherent transition radiation emitted at wavelengths longer than and equal to the whole bunch length.

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.
