Abstract
The relaxation around localized centers to the RES in ionic crystals, after femtosecond excitation, is reported in the time range from 10 f s up to 30 ps, for the case of longlived excited bound electrons (10−6–10−3 s). The excited electrons, the neighboring ions and the host crystal ions form a complex system, whose non linear dynamics is resolved numerically with a method which allows to study centers with a rich electronic structure. One of the output is the ballistic propagation here reported of the initial pulse (as generated by the femtosecond light) from the impurity space to the crystal.
