TLDR
In this paper, an optical pulse is passed through a nonlinear dispersive delay line, which chirps the pulse by the nonlinear process of self-phase modulation and simultaneously and interactively broadens the pulses by the process of group velocity dispersion.Abstract:
An optical pulse is passed through a nonlinear dispersive delay line, which chirps the pulse by the nonlinear process of self-phase modulation and simultaneously and interactively broadens the pulse by the process of group velocity dispersion. The broadened and chirped pulse is then passed through a linear dispersive delay line, which compresses the pulse to a width less than the original pulse. By making the optical pulse suitably intense, a single-mode optical fiber may act as the nonlinear dispersive delay line. A near-resonant atomic vapor cell or a grating pair may act as the linear dispersive delay line.read more

Electronic Mechanism for Production of Self-Phase Modulation
TL;DR: In this article, the authors show that the self-phase-modulation (SPM) mechanism must respond on a sub-picosecond scale, which is consistent with a theoretical model based on an electronic mechanism.

Optical pulse compressors employing modulations affecting the two-photon dispersion of an atomic gaseous medium
Gary C. Bjorklund,Paul F. Liao +1 more
TL;DR: In this paper, two different pulse compressors for relatively intense optical beams differ from the prior art both in employing a two-photon dispersion effect and employing a different set of modulations than is conventional for "chirped" pulse compressor.
