First Measurement of the Non-instantaneous Response Time of a χ(3) Nonlinear Optical Effect
The third harmonic of a few-cycle pulse, generated at different dielectric surfaces, is investigated using interferometric frequency-resolved optical gating. We present direct experimental evidence for a non-instantaneous nonlinear response in a TiO2 thin film whereas surface third-harmonic generati...
