INTERACTION OF ULTRASHORT INTENSE ELECTROMAGNETIC PULSES WITH MATTER

Abstract: 

The aim of the project is the establishment of a research network among Greek Academic institutions in the field of ultra-short electromagnetic (EM) pulse generation and their interaction with matter, in order to conduct inter-disciplinary research crossing through the borders of ultrafast optics, atomic and molecular physics, chemical dynamics, surface and materials science.

The participating scientists have extensive experience in cutting edge research such as the generation of ultra-short coherent EM pulses, the interaction of strong laser fields with atoms, molecules, clusters and surfaces, the development of multi-dimensional imaging techniques, etc. It is expected that the network will facilitate the transfer of knowledge and the optimal exploitation of the existing infrastructure.

The research plan is divided into three main activities:

  1. Interaction of ultra-short electron and EM pulses with atoms, molecules and molecular clusters, including a) molecular alignment and orientation induced by laser pulses, b) molecular dissociation and isomerization processes using high-order harmonics and pulsed electron diffraction and c) comparative study of atomic ionization and molecular dissociative ionization under 7fs and 35fs laser pulses.
  2. Production via high-order harmonic generation of XUV attosecond pulses (?»<30nm), characterization and application in the study of ultra-fast dynamics in atoms and molecules.
  3. Comparative study of the non-linear optical properties at nanostructured surfaces under ns, ps and fs laser pulses in order to resolve the contribution of the physical processes involved.

The expected results of the project will contribute to the deeper understanding of fundamental physical processes at ultrashort time and length scales, while at the same time support state-of-the-art technological developments such as the taming of single attosecond pulses, the ultrafast electron diffraction and multi-dimensional imaging techniques.
