摘要：

Enhanced electron-positron (e - e +) pair production using two obliquely incident lasers interacting with a solid target is investigated through multi-dimensional particle-in-cell (PIC) simulations. Two obliquely incident lasers can strengthen the laser-hole boring effect, which enhances the reflected focusing laser field and the consequent quantum electrodynamics effects. PIC simulations show that by using two 10 PW-scale lasers, a high-yield (3 × 1010) overdense (∼1022 cm-3) positron beam can be generated and laser to pair energy conversion...
