Abstract

A new technique for measuring the time- and frequency-dependent intensities and phases of correlation functions of broadband, non–transform-limited (noisy) light is presented. It is based on others’ successful previous efforts to measure the intensities and phases of short pulses by frequency-resolved optical gating. It is shown that a simplified algorithm based on the original algorithm for frequency-resolved optical gating is sufficient for the recovery of correlation functions. The first experimental realizations of this technique are presented, and the recovered noisy-light correlation functions are shown. By way of illustration, the dispersion of water is quantified. Applications to interferometrically time-resolved nonlinear optical spectroscopies are discussed.
