摘要：
A scheme of two sequent laser pulses irradiating a thin solid aluminum target to generate electronpositron pairs via the multi-photon Breit-Wheeler (BW) process is proposed, in order to ease the usual requirement of the laser intensity. 2D and 3D particle-in-cell simulations show that the peak intensity of the laser pulses used in our scheme is only half of that in the case of one laser pulse with a peak intensity of 2 x 10(23) W/cm(2), but the positron yield is one order higher than that of the latter, which is around 3.7894 x 10(7) and has a maximal density of 3.134 x 10(22) cm(-3) when the time interval between the two pulses is set to Delta t approximate to 2T(0). Therefore, our scheme provides a helpful suggestion for the observation of the BW process in laboratories. Published by AIP Publishing.
