Time-of-flight cross correlation on a detector array for ultrafast packet detection.


Ultrashort optical pulses are characterized by measurement of correlation functions of the field. A first-order autocorrelation measures the Fourier transform of the power spectral density of the field. Nonlinear autocorrelations must be used to determine pulse duration and shape accurately. Despite the variety of correlator designs,1-5 the usefulness of… (More)
