The instantaneous Kerr-effect is used to rotate the polarization of the signal pulse \(E(t)\) during the presence of the gate pulse \(E(t - \tau)\) proportional to the intensity of the gate pulse [5]....The instantaneous Kerr-effect is used to rotate the polarization of the signal pulse \(E(t)\) during the presence of the gate pulse \(E(t - \tau)\) proportional to the intensity of the gate pulse [5]. The setup to measure the Frog-trace is identical with the setup to measure the intensity autocorrelation function (Figure 10.1) only the photodector for the second harmonic is replaced by a spectrometer (Figure 10.18).
