We predict that excitation of a nanosystem with a
correspondingly phase-modulated femtosecond pulse
can cause concentration of the excitation energy at
a small part of that nanosystem . The location of
the excited site is coherently controlled by the
distribution of the phase along that pulse, distinct
from the ``Ninth Wave'' effect . We discuss unique
possibilities of using this in applications, in
particular, for nanoscale ultrafast computing and
nano-lithography. The theory is based on the Green's
function method in the spectral representation [3,4]
employed as an analytical approach and implemented
as a high-efficiency numerical method in the real 3D
