Attosecond real time observation of ionization and electron
... For many intra-atomic processes, femtosecond temporal resolution is not yet satisfactory. Attosecond science holds the promise to push the available temporal resolution by at least an order of magnitude and allows extending conventional ultrafast spectroscopy and strong-field coherent control from t ...

The gain is highest at points, where the phase matching is optimized, which leads to a threepeak spectrum for this particular OPCPA system. The ability to tune both θ and α provides a high degree of contro ...
