Scaling and design of high-energy laser plasma electron acceleration
Figures & Tables(4)
Fig. 1. A comparison of measured electron beam energies in laser wakefield acceleration with the energy scaling as a function of the operating plasma density for (a) the self-guided case in the bubble regime at laser wavelengths of 800 nm (solid line) and 1057 nm (dashed line) and (b) the channel-guided case in both the quasi-linear regime (dashed line) and the bubble regime (solid line). The experimental data are plotted with filled squares for 
and the open square for 
in (a), and with filled circles for 
in (b).
Fig. 2. Electron beam energy spectra obtained from the experiment[6], where a 212-TW, 60-fs laser pulse is focused on a 
spot radius of 
producing 
at the entrance of a gas jet for three cases consisting of (a) a 4-mm long single stage with 
, (b) a 10-mm long single stage with 
and (c) two stages comprising a 4-mm long injector with 
and a 10-mm long accelerator with 
.
