It's worth noting that gigawatt peak power in an ultrafast laser is not special, but that gigawatt peak power in the x-ray region is special. In larger wavelangths (i.e. visible or near-IR), you can get this level of peak power from commercial laser systems (e.g. https://www.spectra-physics.com/products/ultrafast-lasers/spitfire-ace?cat=scientific&subcat=amplifiers https://www.spectra-physics.com/products/ultrafast-lasers/sp...)
