Atomic ionisation dynamics in strong laser fields — •M. Dammasch, U. Eichmann, and W. Sandner — Max Born Institut, Berlin, Germany
Experimental investigations of atomic ionisation dynamics at high laser intensities above 1016W/cm2 are only scarce. Using the MBI high intensity laser facility we have investigated the ionisation dynamics of atoms at weakly relativistic laser intensities. We present laser intensity dependent total ion yield measurements on quasi He-like ions and rare gas atoms. We will discuss the influence of the relativistic continuum on the ionization process. Furthermore we will discuss the possibility to determine high laser intensities directly from ion yield measurements.
