Ultrafast optical response of plasmonic structures beyond the perturbative regime: evidence of universal saturation dynamics

The transient optical response of gold nanorods is investigated beyond the perturbative regime. Ultrafast pump-probe spectroscopy and semiclassical modeling of hot electrons reveal a universal mechanism presiding over the saturation of nonlinear plasmonic effects.
