High-quality stable electron beams from laser wakefield acceleration in high density plasma
http://journals.aps.org/prstab/abstract ... .17.011301
In summary, a stable, background-free, quasimonoenergetic
electron beam has been demonstrated from self-injected
laser wakefield acceleration at high plasma density
using a sub-10 TW power, 45 fs duration Ti:sapphire laser.
The experimental results open a way to easily use energetic
electron beams produced with small laser facilities for
applications.

Last I heard of laser wakefield accelerators is they produced very high energy beams in a compact source, useful for physics experiments. I also have the impression that they have very low efficiency, kind of like most lasers. Fusion reactors tend to favor high current from much lower energy beams.
