Abstract
The generation of ultrarelativistic positron beams with short duration (), small divergence (), and high density () from a fully optical setup is reported. The detected positron beam propagates with a high-density electron beam and 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.

Published 20 June 2013
Dense electron-positron streams, similar to those found in astrophysical jets, can be made using a relatively simple tabletop laser setup.
