WebInterferometric and intensity autocorrelations by third-harmonic generation for the measurement of ultrashort optical pulses are demonstrated. The third-harmonic signal is generated by tight focusing of the ultrashort pulses upon the surface of an ordinary glass slide, replacing the high-optical-quality nonlinear crystals used in conventional second … A special case in which the number of photons in the interaction is , if all the photons have the same frequency . If they have different frequency, the general term of four-wave mixing is preferred. This process involves the 3rd order nonlinear susceptibility . Unlike SHG, it is a volumetric process and has been shown in liquids. However, it is enhanced at interfaces. scrooge with george c scott movie
