Description
Recent all-optical multi-GeV laser wakefield acceleration (LWFA) demonstrations have been enabled by University of Maryland's development of meter-scale supersonic gas jets and low-density plasma waveguides. This poster presents a review of our recent LWFA efforts, including gas jet development, experiments and simulations to benchmark plasma waveguide generation, a new 3-stage model for relativistic pulse propagation in meter-scale waveguides, and recent high efficiency LWFA experiments. These experiments demonstrate sub-milliradian divergence electron bunches with integrated charge >1nC above 1 GeV, and energy spectra including ≲ 10 pC features of ~10 GeV, representing a laser to electron conversion efficiency of at least ~30%.
