摘      要：In order to reach the highest intensities,modern laser systems use adaptive optics to control their beam ***,the focal spot is optimized after the compression stage of the system in order to avoid spatio-temporal *** also requires a wavefront sensor after the compressor,which should be able to measure the wavefront *** PHELIX,we have developed an ultra-compact post-compressor beam diagnostic due to strict space constraints,measuring the wavefront over the full aperture of 28 *** system features all-reflective imaging beam transport and a high dynamic range in order to measure the wavefront in alignment mode as well as on shot.
