Progress in the laser technology is leading to increasingly high intensities on target. Thus, laser facilities can reach so high power nowadays than classical physics is insufficient to describe the laser-matter interaction, as quanto-electro dynamic (QED) effects begin to appear.
There have been many theoretical attempts to describe this phenomena, and PIC codes, which simulate the laser-matter interaction, have been implemented with QED modules to take into account this new physical effects.
While PIC codes have been extensively use to predict behavior in future experiments, it has become increasingly important to validate the different models which have been implemented. Additionally, comparing their results with an experiment would allow to discriminate between these models, and would lead to further understanding of the physics.
Through this allocation, we intend to determine to which extend such an experiment can be realized in laser-solid interaction. Are the current laser facilities sufficient for carrying out this comparison and statistically clearly identify QED models? Else our aim would be to establish the intensity threshold that would be necessary to achieve.
