Abstract
We report optical modulation effects on second harmonic generation (SHG) in C60 films. It was observed that a large second harmonic response of C60 films (in a corona poling field of 5.5 kV at a nominal temperature of 140 °C) was almost completely suppressed when the film was illuminated with a second visible-light source (pulsed or steady state). The magnitude of the SHG suppression was measured as a function of the wavelength and intensity of the second source. By scanning the time interval between a "suppression" pulse and the SHG generation pulse we found that the lead time required for the suppression effect is about 250 ps.
