Abstract

Recently, we developed a simple and general technique, which we call Frequency-Resolved Optical Gating (FROG), that succeeds in measuring the full intensity and phase evolution of an individual, arbitrary ultrashort pulse.1-3 In brief, FROG involves measuring the pulse spectrogram, i.e., the spectrum of the signal pulse in an auto- or cross-correlation using any instantaneous nonlinearity, yielding signal intensity vs. delay and frequency. This trace can then be shown to fully and uniquely characterize the pulse—the pulse extraction problem is equivalent to two-dimensional phase retrieval, a solved problem from image science.
