The ionization of silver clusters exposed to pairs of
intense femtosecond laser pulses strongly depends on the optical delay.
Enhanced production of a certain atomic charge state z is obtained by a
z-dependent delay. This may open a possible
route to control the excitation process and populate specific
charge states. The optimum pulse separation which maximizes the generation
of highly ionized species varies by more than one order of magnitude when
the mean size of the clusters increases from 
to 
. Semiclassical Vlasov
simulations applied to a model system reveal the importance of the initial ionic
motion in the ionization process.
