| 中文摘要 | Recent experiments and simulations have demonstrated effective CO2 laser acceleration of quasi-monoenergetic protons from thick gaseous hydrogen target (of thickness tens of laser wavelengths) via hole boring and shock accelerations. We present here an alternative novel acceleration scheme by combining laser radiation pressure acceleration with shock acceleration of protons in a thin gaseous target of thickness several laser wavelengths. The laser pushes the thin gaseous plasma forward while compressing it with protons trapped in it. We demonstrated the combined acceleration with two-dimensional particle-in-cell simulation and obtained quasi-monoenergetic protons similar to 44 MeV in a gas target of thickness twice of the laser wavelength irradiated by circularly polarized CO2 laser with normalized laser amplitude a(0) = 10.
