Atomic Cluster Ionization and Attosecond Generation at Long Wavelengths

Abstract

The primary aim of this project was to better understand the laser-cluster interaction in the mid-IR range for generating high-order harmonics and evaluate clusters as an alternative source of soft x-rays and attosecond pulses. Clusters as a high-order harmonic generation (HHG) medium was first proposed due to the potential benefits caused by the high local and low global densities by which a large fraction of the incident light can be efficiently stored in the cluster. In fact, early studies claimed that clusters produced higher HHG yield and higher cutoff energy compared to an atomic target. Accordingly, we have first aimed at verifying the cluster as a "better" source by understanding the HHG mechanism in these nano-solid targets.
