We review recent experimental results on the path to producing electron–positron pair
plasmas using lasers. Relativistic pair-plasmas and jets are believed to exist in many
astrophysical objects and are often invoked to explain energetic phenomena related to
Gamma Ray Bursts and Black Holes. On earth, positrons from radioactive isotopes or
accelerators are used extensively at low energies (sub-MeV) in areas related to surface
science positron emission tomography and basic antimatter science. Experimental platforms …
