The fission-fusion reaction mechanism was proposed in order to generate extremely neutron-rich nuclei close to the waiting point N = 126 of the rapid neutron capture nucleosynthesis process (r process). The production of such isotopes and the measurement of their nuclear properties would fundamentally help to increase the understanding of the nucle...

When an ultrashort laser pulse is tightly focused to a size approaching its central wavelength, the properties of the focused spot diverge from the diffraction limited case. Here we report on this change in behavior of a tightly focused Petawatt class laser beam by an F/1 off-axis paraboloid (OAP). Considering the effects of residual aberration, th...

Relativistic electron beams driven by laser wakefield acceleration were utilized to produce ultrashort neutron sources. The experiment was carried out on the 38 fs, ∼0.5 J, 800 nm Ti:Sapphire laser in the 10 TW UT³ laser lab at University of Texas at Austin. The target gas was a high density pulsed gas jet composed of 90% He and 10% N2. The laser p...

We explore the next generation of tunneling ionization rate measurements and above-threshold ionization experiments at intensity ranging from 10^20 to above 10^23 W/cm^2. In this regime, it is thought that relativistic effects begin to play a role in the tunneling process. Electrons "born" into the laser field at peak strength will be accelerated to GeV energies over distances of microns.
