Exotic atoms in superintense laser fields

Abstract

The interaction of very strong laser fields with hydrogenlike atomic systems is analyzed theoretically. It is shown that the usual magnetic field-induced limitations for efficient recollisions can be overcome by employing exotic atoms rather than ordinary ones. In this way not only high-harmonic radiation in the MeV regime could be produced, but also laser-induced nuclear effects and particle reactions come into the reach of near-future laser facilities.
