$1 Photograph of two large-area 1780 lines/mm diffraction gratings ( 420 mm × 450 mm ) used at high incidence in a pulse compressor for the high-energy PETAL laser [79]. The diffraction gratings are made of dielectrics; see Section 6.1b.$ Source: Nicolas Bonod, Jérôme Neauport, "Diffraction gratings: from principles to applications in high-intensity lasers," Adv.
