Laser wakefield acceleration (LWFA) of electrons occurs when an intense short laser pulse focused in an underdense plasma drives in its wake a plasma wave with an amplitude large enough to trap and accelerate electrons. Relativistic electron bunches are easily obtained through this mechanism and have given rise to a large number of studies and publications. Despite these efforts, the...
