This seminar will include both experimental and theoretical topics of ultrafast laser ablation. In the first part, fundamental physics of ultrafast laser-material interactions will be discussed, which include photon-induced microscale energy transport and mass ablation processes that span many orders of magnitude in time scales. In the second part, selected applications of ultrafast laser technologies will be covered.  The topics will include controlled growth of one-dimensional nanomaterials and realization of nanostructured organic light-emitting devices.
