We investigate the extension of self-injecting laser wakefield experiments to the regime that will be accessible with the next generation of petawatt-class ultrashort pulse laser systems. Using nonlinear scalings, current experimental trends, and numerical simulations, we determine the optimal laser and target parameters, i.e., focusing geometry, plasma density, and target length, that are required to increase the electron beam energy (to >1 GeV) without the use of external guiding structures.

, 2008, Proton and ion acceleration by an ultrafast TW CO<inf>2</inf> Laser: Proof-of-principle experiments

Results on proton acceleration by an ultrashort TW CO2 laser interacting with Al foils show 2proton energy spectra substantially different from those obtained with solid-state lasers, due to the laser's different wavelength and polarization. © 2008 Optical Society of America.
