    "abstract": "Through examining the product of the mathematical variance of intensity with\nrespect to time and frequency, we arrive at a temporal characterization of\nlaser pulses through parameters for pulse duration, group delay dispersion and\ntemporal form. These statistics, which are sufficient to predict subsequent\npulse behavior, are recoverable in a simple experiment, measuring the\ntwo-photon-induced photocurrents in three nonlinear diodes. With only two\nphotodiodes, we demonstrate that pulse durations as low as several tens of\nfemtoseconds can be easily measured in a single shot if the usual assumptions\nof pulse form and dispersion are made as in the more difficult autocorrelation\nsetup.",
