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 [1]. The location of the excited site is coherently controlled by the distribution of the phase along that pulse, distinct from the ``Ninth Wave'' effect [2]. 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 space.
