a Measured and simulated autocorrelation trace from Eq. (3). b Illustrates the calculated power spectrum of both the measured and simulated signals from (a), see text and “Methods” for details. Moreover, the calculated electric field with FWHM pulse duration of 37.5 ps used in (a, b) from Eq. (3) is plotted in (c) with normalized units, see Methods. THz energy as a function of pump intensity is shown in (d) for two data sets with fixed pump pulse duration and also for fixed pump energy. The error bars on our figures reflect the square root of the sum of the squares for these uncorrelated errors (see “Methods”).
