Gamma ray and Electron- positron pairs generation based on ultra-intensity and ultra-short laser

Abstract

With the rapid development of the ultra-short and ultra-intensity laser techniques, the intensity of laser has reached 1023W/cm2, which offers a tool to investigate the laser matter interaction in QED regime. On this basis, it is feasible to generate gamma rays and electron positron pairs in terms of strong field laser plasma interaction. In this paper, the state-of-art configuration and schemes for above particles generation are discussed. Besides, the limitations as well as future direction are also analysed. These results shed light on further exploration of laser-plasma phenomena in strong field physics.
