AB - <p style="text-align: justify;">In this paper, we model laser-gas interactions and propagation in some extreme
regimes. After a mathematical study of a micro-macro Maxwell-Schrödinger
model [1] for short, high-frequency and intense laser-gas interactions, we propose to
improve this model by adding a plasma equation in order to precisely take into account
free electron effects. We examine if such a model can predict and explain complex
structures such as filaments, on a physical and numerical basis. In particular, we
present in this paper a first numerical observation of nonlinear focusing effects using
an ab-initio gas representation and linking our results with existing nonlinear models.</p>
