Many 20-100 Petawatt laser projects have been proposed worldwide, and some are under construction now. Considering the development of ultra-intense lasers in the post-10/100-Petawatt era, several technological developments have been presented by many groups. Here, I am going to introduce the technology of the wide-angle non-collinear optical parametric chirped pulse amplification (WNOPCPA) and, especially, the prototype facility construction in Shanghai, China. The goal of this technology is to realize near-octave ultra-broadband high-energy amplification for future near-single-cycle Exawatt-class lasers, and that of the prototype facility is to demonstrate the performance in experiments. In this talk, I will also introduce the near-octave ultra-broadband gratings for pulse stretching/compression and near-octave ultra-broadband mirrors for beam propagation those developed for our WNOPCPA laser.
