High Harmonic Generation from Molecules: Prospects for ultra-fast imaging of molecular structure and dynamics — •Jonathan Marangos — Imperial College London, UK

High harmonic generation (HHG) in a strong laser field is a coherent and highly non-linear process. It is initiated by laser ionisation and the key component of the process is the laser driven recombination of an energetic (10 - 100 eV) electron with the molecular ion. This results in emission of a broad spectrum of coherent XUV radiation that encodes within it information on the electronic and nuclear wavefunctions of the molecule. In this presentation I will talk about recent results from my own group using molecular HHG for measuring molecular structure and dynamics and speculate about the future prospects for this method for attosecond reolved atomic scale imaging of matter.
