TLDR
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).
Abstract
The grating and prism compressors are studied for the case of finite beam size by using the Kirchhoff–Fresnel integral and an amplitude transfer operator for the grating and prism. The results show that, even for well-collimated beams, pulse broadening may occur (mainly because of the wavelength dependence of the lateral walk-off). Methods to avoid the different types of distortions appearing in these systems are discussed.

The prospects for ultrashort pulse duration and ultrahigh intensity using optical parametric chirped pulse amplifiers

TL;DR: In this paper, the properties of optical parametric amplifiers are presented to show that, in addition to their use in providing tuneable pulses, they can form the critical component in systems generating shorter pulse duration with higher power and intensity than is possible with existing systems.

Negative group-velocity dispersion using refraction

TL;DR: In this article, it was shown that a negative contribution to the group-velocity dispersion always accompanies angular dispersion and structures, such as slabs and prisms, that use this contribution to provide adjustable group velocity dispersion.
