摘要：

We demonstrate that ultrafast modulation of second-harmonic (SH) intensity from a Langmuir-Blodgett (LB) film consisting of a ruthenium complex is possible by laser irradiation of the films. The switching of the second-harmonic intensity is demonstrated to occur in less than 2 ps by a picosecond pump-probe experiment. Results from time-resolved fluorescence studies of the LB film correlate quantitatively with those of the second-harmonic generation (SHG). The mechanism of the photoinduced SHG switching is ascribed to the change of molecular hyperpolarizability of the ruthenium complex on going from the ground state to the excited state.
