“…Laser based accelerators (Tajima et al, 1979;Baiwen et al, 2004;Giulietti et al, 2005;Kruer, 1988;Shi et al, 2007;Karmakar & Pukhov, 2007;Liu et al, 2009) and laser induced fusion (Canaud et al, 2004;Deutsch et al, 1996Deutsch et al, , 2008Regan et al, 1999;Hora, 2007;Imasaki & Li, 2008;Hong et al, 2009;Stancalie, 2009) using laser-plasma interaction (Hora & Hoffmann, 2008;Borghesi et al, 2007;Laska et al, 2008;Dromey et al, 2009;Hong et al, 2009;Kline et al, 2009;Kulagin et al, 2008;Malekynia et al, 2009;Nakamura et al, 2008;Sharma & Sharma, 2009) are attracting a lot of interest. The inertial fusion program requires the anomalous absorption of laser light by the plasma, whereas the plasma-based beat-wave accelerator concept relies on the radiation induced high phase velocity electron plasma (Langmuir) waves that can accelerate electrons to extremely high energies.…”
