| Research Abstract |
Motions of propagation of surface plasmon wave packets on metal films are visualized at a femtosecond time resolution by a newly developed time-resolved two-photon fluorescence microscopy using a 10 fs infrared pulse laser as the excitation source. Analyses of the time-resolved moviesquantitatively determine the group velocity, the phase velocity, the lifetime, the propagation length, and the deformation of wave packets. These experimentally determined parameters are in good consistency with the values estimated from an eigenmode function of the multilayer system.
