Laser Wakefield acceleration with high relativistic pumps

Abstract
Preliminary scaling laws are found for the laser wakefield accelerator in the very non‐linear regime where the normalized laser pump strengh V osc c=e E 0/mω0 c≳1. Two important non‐linear effects are an increase in the wake phase velocity (and hence the particle dephasing length) and an increase in the laser pulse length for optimal wake excitation. Application of the results to the proposed Livermore High‐Brightness Lasers (HBL) is discussed here and in the accompanying paper by C. B. Darrow, et al. A preliminary 1‐D PIC simulation is presented.
