Project Title

Photoionization Dynamics in Ultrashort Duration UV and Vacuum-UV Laser Fields – ‘The Ultrafast and The Furious’

Abstract

The PhD project is to investigate the general area of the interaction of laser ablated vapours and plasmas with ultrashort UV and VUV pulses from a variety of laboratory and FEL facility sources. In DCU the methodology for generating laser ablated atomic vapours and lowly charged plasma plumes will be developed.

MORE

The dual laser plasma (DLP) technique will be used to investigate VUV and XUV photoabsorption of these plumes. One Nd:YAG laser is used to generate the back-lighting plasma source of continuum radiation, while a second laser is used to generate an absorbing plasma from the element.

The spectral data will be obtained by firing the back-lighting Nd:YAG laser alone and then firing both lasers together. In Southampton (ORC): Few femtosecond coherent XUV and VUV high harmonic generated (HHG) pulses will be used to ionize laser ablated plumes and the products measured using ion and electron spectroscopy.
