Characterization of ML mirrors to compress attosecond pulses

Multilayer mirrors  were designed to compress EUV pulses below 50 as. The mirrors  have been characterized  in amplitude and in phase in the EUV range by measuring the Reflectivity and the Total Electron Yield. The very good overall agreement with simulated phases allowed to estimate experimentally the time spent by an attosecond pulse in the multilayer mirrors during the reflection process.

A theoretical and experimental study was performed on time domain optimized multilayer mirrors to obtain sub-50 as pulses. This study was done by controlling the energy dispersion over a spectral range large 120 eV.  The mirrors were characterized in amplitude and in phase by using the total electron yield standing wave method.  This allowed to reconstruct the attosecond reflected electric field from these multilayer mirrors . Moreover, a theoretical study highlighted that the tolerance of the mirrors to variations of the experimental conditions was good. In particular, the mirrors can ensure an efficient pulse compression in a very large range of angles of incidence. The very good overall agreement with simulated phases allowed to estimate experimentally the time spent by an attosecond pulse in the multilayer mirrors during the reflection process.
