Abstract

High Harmonic Generation provides a coherent source of extreme ultraviolet photons. Tuned to the correct energies, these photons can be resonant with electrons associated with the magnetic moment of many magnetic materials. This thesis provides an investigation into performing ptychographic imaging with a high harmonic source as a step towards performing high resolution imaging of magnetic domains. Three ptychography codes (Ptychodactyl, PyNX, and tike), are compared for image reconstruction quality and ease of use. Tike and Ptychodactyl prove more successful than PyNX. These first two programs reconstruct data from a simple helium-neon laser setup with great success, and tike demonstrates promise with data gathered from the high harmonic generation setup.
