Development of an Ultrashort Pulse Soft X-Ray Light Source
Abstract
The original aim of this work was to develop an ultrashort pulse soft x-ray light source. In the course of exploring laser produced plasmas and high order harmonic generation sources this work uncovered a wealth of new physics in the realm of high intensity laser-atom photoionization. The study of the absorption of many photons leading to ionization is of vital importance to understanding novel light sources. This project discovered and exploited a new restricted geometry measurement technique and methodology that has allowed a more direct comparison of experimental data with theory. During the last year the project produced several publications on using restricted geometry detection and uncovered new photoelectron features in kinetic energy spectrum measured from photoionization with high intensity laser pulses resulting from the absorption of over 30 photons by a single atom. These measurements have raised new questions concerning the role of doubly excited states and electron-electron correlations in high intensity photophysics.
