This paper is devoted to the improvement of a numerical Maxwell-Schrödinger system, modeling the intense, high frequency and ultrashort laser-gas interaction and propagation, and previously presented in [3]. To this original model is added an equation of evolution of the free electron density, allowing then to describe precisely the current density in the Maxwell equations. Free electrons are obtained by absorption of the wavefunctions at the boundary of their corresponding TDSE computational domain. As a consequence higher intensity and longer pulses can then be considered using this new model compared to [3]. The new computing strategy is then presented, following [4].
