Resonant grating pulse compression element with 99% flat top efficiency for high average power femtosecond laser machining

Abstract : Top hat diffraction efficiency in an all-dielectric SiO2/HfO2 grating femtosecond pulse compression grating is demonstrated with a close to 100% flat top over more than 20 nm around 800 nm wavelength. New perspectives are open for high average power femtosecond laser machining.
