Temporal evolution of the laser electric field at any point of the transverse plane of a bimode CO2 laser is reconstructed using three fast detectors located at different points in the transverse plane. We investigated a situation in which the dynamics is particularly rich i.e. displaying different periodic and chaotic regimes. A comparison between numerical analysis and experiments allows us to perform a critical evaluation of the method.
