Abstract:
Advances in high intensity laser systems enable large energies to
be delivered to targets simultaneously with kilohertz repetition rates,
making laser driven x-ray sources much more accessible. However, the
targeted needed for full utilization of such sources is still lacking. In
this seminar, I will explain the process of x-ray generation via the high
harmonic generation process and how high brightnesses can be achieved
through macroscopic phase matching. I will then show the need for
controllable target densities, where I demonstrate that using carefully
designed 3D printed has jets, high brightness x-ray beams can be generated.
Finally, I will show that such a source enables deep investigations into
novel polarization schemes that have been unable to be observed before,
such as the wavelength scaling of phase matching for vector polarization
states.
