Abstract: Monitoring both temporal and spatial distributions of transitory electro-magnetic fields represents a challenge with frontier applications. High-power laser-matter interaction is just one of the examples in which such transient electro-magnetic fields are produced, and where such a field monitoring would be of a real interest in characterizing the interaction itself, an interaction otherwise relatively hard to monitor and control. Starting from some previously developed theoretical and experimental correlations between High-Power Laser-Matter interaction parameters and associated pulsed electromagnetic fields (EMP) parameters, here we present some results on magnetic field spatial and temporal measurements, for 2D areas of about 1 cm² and temporal duration of ms order. System calibration results were performed based on material theoretical parameter values as well as experimentally measured parameter values. Field measurement experimental values are compared with field theoretical calculations as well as other experimental results obtained with different ‘standard’ calibrated tools (e.g. Hall probe). Furthermore, based on Electro-Optical materials, similar results could be obtained for electric field spatial and temporal variations. Comparative results for such systems are presented and discussed, as well as perspectives of such measurement and monitoring techniques in relation with high-power laser-matter interactions characterization and diagnosis.

Keywords: Non-linear optic materials, transitory electro-magnetic field monitoring, laser-matter interactions.
