Extremely simple techniques for the complete spatio-temporal characterization of extremely complex ultrashort light pulses

We describe four experimentally simple, accurate, and reliable methods for measuring both simple and very complex ultrashort light pulses. Although each method comprises only a few optical elements, they permit the measurement of extremely complex pulses with time-bandwidth products greater than 65,000. Two techniques measure the complete spatio-temporal intensity and phase, E(x,y,z,t), of ultrashort pulses, one in and near a focus and the other for a single pulse.
