“…The multiple stage compression method based on spectral broadening using SPM in the bulk of material with the further recompression of the chirped pulse is able to deliver even shorter pulse duration below 10 fs without energy sacrificing [37]. Further development of this idea, with SPM in thin film below 1 mm and much higher intensity (up to tens of TW/cm 2 ) was suggested [38].…”

Ultra-high peak power laser systems are applicable in new and very promising areas, such as charged particles acceleration and inertial confinement of the fusion nuclear reaction. First one could be used as effective secondary source of Y and X-ray beams, which have multiple applications in industry and medicine if repetition rate will be increased, the last one could serve as a source of unlimited energy after transforming in to the power plants. New technologies are able to significantly increase the output peak power due to extraction of the higher energy extracting during pumping (EDP). The record of extracted energy about 200 J and output power of 5 PW were reached with this technique. Polarization Encoded Chirped Pulse Amplification (PE-CPA) technique as well as two stages of compression produced shorter pulse duration also are presented in this chapter. Besides, the capability of combination of the EDP method and the Thin Disk (EDP-TD) applied to Ti:Sa amplifiers to produce the higher repetition rate in the PW-class laser systems, as well as the results of the proof-of-principal experiments will be demonstrated.

“…In Ref. [37], the next logical step was suggested to use super-Gaussian beam profile due to its higher uniformity. If a laser beam has spatially uniform intensity, SPM can be used in nearfield without spatial filtering and consequently eliminating constraints of the laser energy and transmission efficiency.…”

“…Despite a huge number of works (see, for example, references in the review paper [3]), pulses were compressed only with mJ energy, and the energy efficiency was less than 50%. In the recent years, quite a few experimental results were obtained [9][10][11][12][13][14][15][16], in which CafCA was successfully implemented for pulses with an energy of 1-18 J and energy efficiency close to 100%. An important impetus for these studies was the proposed and experimentally confirmed method of suppressing small-scale self-focusing [17,18], even at large values of the B-integral…”

“…In experiments, different materials were used as a nonlinear medium, e.g., glass [9], polyethylene terephthalate [10], but in the majority of works it was silica [11][12][13][14][15][16]. As shown in [3], a compressed pulse will be shorter at a minimal ratio of the group velocity dispersion k 2 to the nonlinear index of refraction n 2 .…”

The input pulse of the laser PEARL with energy of 18 J and pulse duration of about 60 fs was compressed to 10 fs after passage through a 4-mm thick KDP crystal and reflection at two chirped mirrors with sum dispersion −200 fs 2 . The experiments were performed for the В-integral values from 5 to 19 without visible damages of the optical elements, which indicates that small-scale self-focusing is not a significant issue. It was shown that, by virtue of the low dispersion of the group velocity, the KDP crystal has some advantages over silica: a larger pulse compression coefficient, especially at a small value of the В-integral (B=5…9), lower absolute values of chirped mirror dispersion, and also a possibility to control the magnitude of nonlinearity and dispersion by changing crystal orientation.

Spectral-broadening of the Apollon PW-class laser pulses using a Thin Film Compression technique within the Long-Focal-Area interaction chamber of the APOLLON laser facility is reported, demonstrating the delivery of the full energy pulse to the target interaction area. The laser pulse at 7 J passing through large aperture, thin glass wafers is spectrally broadened to a bandwidth that is compatible with a 15 fs pulse, indicating also the possibility to achieve sub-10 fs pulses using 14 J. Placing the post-compressor near the interaction makes for an economical method to produce the shortest pulses by limiting the need for high damage, broadband optics close to the final target rather than throughout the entire laser transport system.
