摘要:
Electron-positron (e(-) e(+)) pair plasma generation in the relativistic transparency regime in a thin foil with a fixed thickness irradiated by two counter-propagating laser pulses is investigated through multi-dimensional particle-in-cell simulations. It is shown that target transparency can significantly enhance the pair generation due to the formation of a stable standing wave. An optimum foil density of 200-280 n(c) (with n(c) being the critical plasma density of the incident laser at the wavelength of 1 mu m) is found for enhanced e(-) e(+) pair generation for laser intensity around 10 P...
