Abstract With the forthcoming 10-100PW laser facilities, laser-driven electron-positron-pair production has gained particular interest. Here a scheme to enhance the generation of dense electron-positron-pairs is proposed and numerically demonstrated, employing double laser pulses at the intensity level of 10^23 W cm^(-2). The first laser accelerates a thin foil to a relativistic speed via the radiation-pressure-acceleration mechanism and a counter-propagating laser irradiates this flying plasma layer. The simulation results indicate that a high-yield and well-collimated positron beam (~5.5×10^10 positrons/pulse, 8.8nC/pulse) is generated with a large peak density(1.1×10^21 cm^(-3) ) by using tens-of-PW laser pulses.
