TLDR
In this article, the authors describe measurements of pulses consisting of only eight optical periods, which were produced by compression with a short optical fiber and a grating pair, by autocorrelation using noncollinear second harmonic generation in a thin crystal of potassium dihydrogen phosphate.Abstract:

Femtosecond pulse shaping using spatial light modulators
TL;DR: In this article, the field of femtosecond pulse shaping is reviewed, and applications of pulse shaping to optical communications, biomedical optical imaging, high power laser amplifiers, quantum control, and laser-electron beam interactions are reviewed.
Journal ArticleDOI
Mode-locking of lasers
TL;DR: The evolution of the theory of mode-locking over the last three and a half decades is reviewed and some of the salient experiments are discussed in the context of theory as discussed by the authors, with two-cycle pulses of a mode-locked Ti:sapphire laser.

Compression of optical pulses to six femtoseconds by using cubic phase compensation.
TL;DR: It is demonstrated that a combination of prisms and diffraction gratings can provide not only quadratic but also cubic phase compensation of ultrashort optical pulses.

Optical wave breaking of pulses in nonlinear optical fibers
TL;DR: A new effect appears in femtosecond optical pulse compression, using single-mode fibers, that is described as optical wave breaking, which often leads to computational instabilities, but careful numerical simulations give results in excellent agreement with experiment.

Grating and prism compressors in the case of finite beam size
TL;DR: In this article, the authors used the Kirchhoff-fresnel integral and an amplitude transfer operator for the grating and prism compressors for the case of finite beam size, and showed that even for well-collimated beams, pulse broadening may occur (mainly because of the wavelength dependence of the lateral walkoff).

Optical pulse compression with diffraction gratings
TL;DR: In this paper, the theory of the diffraction grating pair was developed by expanding the frequency dependence of the phase shift as far as the quadratic frequency term, and the analogy between pulse compression and Fresnel diffraction was treated.

Generation of optical pulses shorter than 0.1 psec by colliding pulse mode locking
TL;DR: 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.

Extreme picosecond pulse narrowing by means of soliton effect in single-mode optical fibers
TL;DR: The narrowing of pulses to widths as small as 0.26 psec by various lengths, short relative to the soliton period, of single-mode, low-loss optical fiber is reported to be in at least semiquantitative agreement with prediction based on the nonlinear Schrödinger equation.

Compression of femtosecond optical pulses
TL;DR: In this paper, the authors describe the generation and measurement of optical pulses as short as 30 fs. The pulses are produced using self-phase modulation in a short 15 cm optical fiber followed by a grating compressor.
