Advanced analysis of spectroscopic signatures of strong oscillating Quasi-monochromatic Electric Fields (QEF) interacting with a preformed laser-produced plasma is presented. The Stark line shape in the presence of a QEF is calculated, the QEF intensity profile throughout the plasma is estimmated. The Stark profiles are calculated using the Floquet-Liouville formalism. The Liouville space and the Floquet theory have been joined together to solve the time-dependent Liouville equation. A second kind of simulations involving PIC kinetic simulations is required for the calculation of the QEF and the exotic features exhibited in the spectroscopic diagnostic. The final spectroscopic analysis of the experimental Al He beta line is performed. The spectroscopic signatures of the QEF show up as prominent satellites, non symmetrical with respect to the unperturbed line and distinguishable from the di-electronic satellites.
