We present the first derivation of quantum and classical Fisher information for attoscience to characterize the laser intensity uncertainty for in situ measurements in strong field ionization. We analytically demonstrate a quadratic dependence of the Fisher informations upon the time the photoelectron is subjected to the laser, which we link to a ‘ponderomotive phase’. We demonstrate that interference effects greatly reduce the laser intensity uncertainty and suggest how to minimize uncertainties in a previous experiment.
