“…[174] , or a multistage CafCA approach as shown in Figure 24. The advantage of multistage CafCA is clearly seen from the simple formulae showing how many times the pulse power may be increased over a single-stage CafCA: [175] . According to it may be reached by only three-stage CafCA, with a conservative value in each stage.…”

In the 2015 review paper ‘Petawatt Class Lasers Worldwide’ a comprehensive overview of the current status of high-power facilities of ${>}200~\text{TW}$ was presented. This was largely based on facility specifications, with some description of their uses, for instance in fundamental ultra-high-intensity interactions, secondary source generation, and inertial confinement fusion (ICF). With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification (CPA), which made these lasers possible, we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed. We are now in the era of multi-petawatt facilities coming online, with 100 PW lasers being proposed and even under construction. In addition to this there is a pull towards development of industrial and multi-disciplinary applications, which demands much higher repetition rates, delivering high-average powers with higher efficiencies and the use of alternative wavelengths: mid-IR facilities. So apart from a comprehensive update of the current global status, we want to look at what technologies are to be deployed to get to these new regimes, and some of the critical issues facing their development.

“…Recently the concept of post-compression, previously demonstrated with low-energy ultra-fast lasers, has been extended to high-energy lasers by A. Zheltikov and G. Mourou et al in order to generate few-cycle, PW and even EW laser pulses, where spectral broadening is achieved with very large and very thin solid-state materials 30 , 31 . This approach of post-compression, for example with large-aperture thin films or thin plates, in ultra-intense lasers are called as thin-film compression (TFC) or compression-after-compressor approach (CafCA), which has been successfully demonstrated and studied in several ultra-intense lasers 32 – 37 .…”

The rapid development of the optical-cycle-level ultra-fast laser technologies may break through the bottleneck of the traditional ultra-intense laser [i.e., Petawatt (PW, 1015 W) laser currently] and enable the generation of even higher peak-power/intensity lasers. Herein, we simulate an ultra-broadband concept for the realization of an Exawatt-class (EW, 1018 W) high peak-power laser, where the wide-angle non-collinear optical parametric chirped-pulse amplification (WNOPCPA) is combined with the thin-plate post-compression. A frequency-chirped carrier-envelope-phase stable super-continuum laser is amplified to high-energy in WNOPCPA by pumping with two pump-beamlets and injected into the thin-plate post-compression to generate a sub-optical-cycle high-energy laser pulse. The numerical simulation shows this hybrid concept significantly enhances the gain bandwidth in the high-energy amplifier and the spectral broadening in the post-compression. By using this concept, a study of a prototype design of a 0.5 EW system is presented, and several key challenges are also examined.

“…This served as an impetus for both theoretical and experimental research in recent years. The theoretical works were aimed at detailed numerical modeling [14,2,18], as well as at expanding the capabilities of the technique. For example, the application of the method for a pulse after wide-angle non-collinear optical parametric chirped-pulse amplification (WNOPCPA) [19], the enhancement of the pulse time contrast simultaneously with its compression [20][21][22][23], and the use of a nonlinear medium with a large n 2 [24].…”

The PEARL laser output pulse with a duration of 60-70 fs was compressed to 11 fs after passing through a 5-mm thick silica plate and reflecting from two chirping mirrors with a total dispersion of -250 fs 2 . The experiments were carried out for the B-integral values up to 19 without damage of the optical elements, which indicates that small-scale self-focusing was suppressed. The results obtained show the possibility of further nonlinear compression scaling to multipetawatt power in pulses with duration commensurate with the field period.
