OAK- (B204)Petawatt solid-state lasers require meter-sized gratings to reach multiple-kilojoule energy levels without laser-induced damage. As an alternative to large single gratings, we have demonstrated that smaller, coherently added (tiled) gratings can be used for subpicosecond-pulse compression. A Fourier-transform-limited, 650-fs, chirped-pulse-amplified (CPA) laser pulse was maintained by replacing a single compression grating with a tiled gratings assembly. Grating tiling provides a means to scale the energy and irradiance of short-pulse lasers.
