Highly efficient γ-ray generation by 10 PW-class lasers irradiating heavy-ion plasmas
文献摘要：
10 PW-class lasers irradiating overcritical plasmas in the quantum electrodynamics regime promise to generate ultrabright γ-ray sources in the laboratory.Here using two-dimensional particle-in-cell simulations,we report highly efficient γ-ray generation in the parameter regime of 10 PW-class lasers at an intensity level of 1023 W cm-2 interaction with heavy-ion plasmas which have large-scale preplasmas.The laser-to-γ-ray(＞1 MeV)energy conversion efficiency reaches close to 60％with an above 1014 γ-photons/pulse.The average γ-photon energy is about 14 MeV with the highest photon energy exceeding 1 GeV.The high-energy γ-photons are mainly directed in the forward direction.We also find that plane target geometry is efficient enough for high power γ-ray radiation,which is beneficial for easing the difficulty of complex target manufacturing and alignment in experiments.
