High laser intensities enable the production of electron-positron pairs from bright gamma rays passing through strong fields. Potentially the most promising approach for all-optical experiments in the near term uses dense but higher…

As the repetition rates of ultra-high intensity lasers increase, simulations used for the prediction of experimental results may need to be augmented with machine learning to keep up. In this paper, the usage of gaussian process regression…

We present simulations which predict significantly higher laser to X-ray efficiencies than those previously found in high intensity (1e20-1e22 W/cm2) laser-solid simulations. The bremsstrahlung emission is shown to last for 10-100 ps, which…
