Abstract
We describe a non-interferometric ultrashort-pulse measurement technique based on frequency-resolved optical gating (FROG) with which pulses can be reconstructed directly, i.e. non-iteratively. With a single-shot FROG setup two different FROG spectrograms are measured, which represent the only information required to reconstruct the amplitudes and phases of two independent input pulses.
