| 内容記述 | We employ the λ3 regime where a near-single-cycle laser pulse is tightly focused, thus providing the highest possible intensity for the minimal energy at a certain laser power. The quantum electrodynamics processes in the course of the interaction of an ultra-intense laser with a solid target are studied via three-dimensional particle-in-cell simulations, revealing the generation of copious γ-photons and electron–positron pairs. A parametric study of the laser polarisation, target thickness and electron number density shows that a radially polarised laser provides the optimal regime for γ-photon generation. By varying the laser power in the range of 1 to 300 PW we find the scaling of the laser to γ-photon energy conversion efficiency. The laser-generated γ-photon interaction with a high-Z target is further studied using Monte Carlo simulations revealing further electron–positron pair generation and radioactive nuclide creation. | |||||
