Ultrafast transient responses in single gold nanorods are visualized in real space by femtosecond pump-probe measurements using a near-field optical microscope. The observed transient images show characteristic features, and the features are strongly dependent on the size of the rod. It is revealed that the features arise from changes in the plasmon-mode wave function upon elevation of the electronic temperature of the nanorod induced by photoexcitation.
