Spectral and spatial phase distorsions induced by mosaic gratings compressor of petawatt laser

In petawatt lasers segmented mosaic gratings are studied to recompress pulses. Alignments of the mosaic elements are crucial. We discuss theoretical model of phase shift and tolerances on alignment are presented
