More than 96% efficiency wide band top-hat diffraction efficiency spectra, as well as more than 1 J/cm2 damage threshold under 50 fs pulses are demonstrated experimentally. This opens the way to high-efficiency Chirped Pulse Amplification for high average power laser machining by means of all-dielectric structures as well as for ultra-short high energy pulses by means of metal-dielectric structures. %G English %L ujm-00381564 %U https://hal-ujm.archives-ouvertes.fr/ujm-00381564 %~ UNIV-ST-ETIENNE %~ X %~ IOGS %~ ENSTA %~ CNRS %~ UNIV-AMU %~ LAHC %~ X-LOA %~ X-DEP %~ X-DEP-PHYS %~ PARISTECH %~ ENSTA_LOA %~ LP3 %~ UDL %~ TEST3-HALCNRS
