(a) A typical image of the fast electrons produced from the interaction of 45 fs duration Ti:sapphire laser pulses focused to 4 × 1016−17 W/cm2, for both p- and s-polarization, on planar copper solid target at oblique incidence of 45° w.r.t. the target normal. (b) The lineout gives the intensity profile of the fast electrons with an HWHM angular spread of 20°.
