N2 - The generation of ultrarelativistic positron beams with short duration (tau(e+) similar or equal to 30 fs), small divergence (theta(e+) similar or equal to 3 mrad), and high density (n(e+) similar or equal to 10(14)-10(15) cm(-3)) from a fully optical setup is reported. The detected positron beam propagates with a high-density electron beam and gamma rays of similar spectral shape and peak energy, thus closely resembling the structure of an astrophysical leptonic jet. It is envisaged that this experimental evidence, besides the intrinsic relevance to laser-driven particle acceleration, may open the pathway for the small-scale study of astrophysical leptonic jets in the laboratory.
