Attosecond pulse shaping using a seeded free-electron laser

We demonstrate amplitude and phase manipulation of the harmonic components of an attosecond pulse train in combination with an approach for its temporal reconstruction. The results presented here open the way to performing attosecond time-resolved experiments with free-electron lasers.

The high intensities in the XUV and X-ray spectral region reached by FELs, combined with the capabilities offered by seeding to independently control and shape the amplitudes and phases of attosecond pulses, are opening new possibilities for the investigation and control of ultrafast nonlinear electronic processes.
