TLDR
Using of Thin Film Compressor for shortening of PW laser pulses was investigated in experiments as mentioned in this paper, where Cascade quadratic nonlinearity in a single KDP crystal can be applied for control temporal parameters of the laser pulses.Abstract:

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Single cycle thin film compressor opening the door to Zeptosecond-Exawatt physics
TL;DR: In this article, a relativistic mirror was proposed to compress a high energy pulse as high as a few hundred Joules in a pulse as short as one optical cycle at 0.8μm.

High-energy pulse compression by use of negative phase shifts produced by the cascade chi((2)):chi((2)) nonlinearity.
TL;DR: A simple optical pulse-compression technique based on quadratic nonlinear media where negative nonlinear phase shifts are generated by phase-mismatched second-harmonic generation, and the phase-modulated pulses are compressed by propagation through materials with normal dispersion.

TL;DR: In this paper, a defocusing lens made of TF12 heavy flint glass was used to generate an almost constant spectral broadening across a Gaussian beam profile, such that the product of the thickness with intensity is constant.

Spatially-uniform temporal recompression of intense femtosecond optical pulses
TL;DR: In this article, a specially designed telescope with defocusing lens and off-axis parabolic mirror, which is working as a nonlinear element and producing self-phase modulation, was implemented for intense (31 TW/cm2) femtosecond laser pulses with Gaussian beam profiles.
