Resumo: | The growth rates of seeded QED cascades in counterpropagating lasers are calculated with first-principles two-and three-dimensional QED-PIC (particle-in-cell) simulations. The dependence of the growth rate on the laser polarization and intensity is compared with analytical models that support the findings of the simulations. The models provide insight regarding the qualitative trend of the cascade growth when the intensity of the laser field is varied. A discussion about the cascade's threshold is included, based on the analytical and numerical results. These results show that relativistic pair plasmas and efficient conversion from laser photons to. rays can be observed with the typical intensities planned to operate on future ultraintense laser facilities such as ELI or Vulcan. |
