Shaping of single-cycle sub-50-attosecond pulses with multilayer mirrors

Abstract : We report on the study of multilayer mirrors designed to compress extreme-ultraviolet pulses below 50 as. The mirrors were optimized in the time- domain to get the wanted pulse shape and duration when combined with a broadband hybrid filter. Moreover they appeared to be very robust to environmental parameters, ensuring a pulse compression in various conditions. We manufactured the mirrors and characterized them on a synchrotron facility both in amplitude and phase. The measurement of the latter was performed using the photocurrent technique, which is the only method allowing one to access to the mirrors absolute spectral phase. This led to a measurement of the offset induced by one of the mirrors on the carrier-envelope phase of attosecond pulses.
