摘要
We consider the production of electron-positron pairs by the interaction of relativistic superthermal electrons, generated by ultraintense laser pulses, with high-Z material. We discuss the laser and target parameters required in order to optimize the pair-production rate. We explore the regime when the pairs, if sufficiently confined, can start to exponentiate in number and explore the feasibility of achieving a pair density approaching 10(21) cm(-3), 1/50 th that of solid-ion density.
