In this study, femtosecond time-resolved measurements of reflectance change were performed to reveal the nonlinear optical response of nitrogen-vacancy-doped nanodiamond on Au thin films. We found that the nonlinear optical response was strongly enhanced due to plasmon resonance with a gold thin film. In this presentation, we will discuss more detail of the time-resolved signal of nonlinear optical response obtained from this study.
