Moving the Frontier of Quantum Control into the Soft X-Ray Spectrum

الملخص EN

The femtosecond nature of X-ray free electron laser (FEL) pulses opens up exciting research possibilities in time-resolved studies including femtosecond photoemission and diffraction.

The recent developments of seeding X-ray FELs extend their capabilities by creating stable, temporally coherent, and repeatable pulses.

This in turn opens the possibility of spectral engineering soft X-ray pulses to use as a probe for the control of quantum dynamics.

We propose a method for extending coherent control pulse-shaping techniques to the soft X-ray spectral range by using a reflective geometry 4f pulse shaper.

This method is based on recent developments in asymmetrically cut multilayer optic technology and piezoelectric substrates.
