Theacceleration of electrons to 0.8 GeV has been observed in aself-injecting laser wakefield accelerator driven at a plasma density of5.5×10¹⁸ cm^-3 by a 10 J, 55 fs, 800 nm laser pulse in theblowout regime. The laser pulse is found to be self-guidedfor 1 cm (>10z_R), by measurement of a single filament containing>30% of the initial laser energy at this distance. Three-dimensionalparticle in cell simulations show that the intensity within theguided filament is amplified beyond its initial focused value toa normalized vector potential of a₀>6, thus driving a highlynonlinear plasma wave.
