a transient, time-delayed, four-wave mixing experiment is performed in strontium vapor under stochastic excitation conditions the first two broad-bandwidth laser pulses are correlated and their delay is adjustable. thus they combine into a non-markovian excitation process with adjustable memory time. one of the correlated pulses is allowed to be strong. in contrast with previous investigations, it is shown both theoretically and experimentally that under strong-field conditions the atoms are not able to keep the excitation memory over time intervals longer than the inverse laser bandwidth
