Surface and bulk contributions to the second-order nonlinearity of gold

We use two-beam second-harmonic generation to separate the surface and bulk contributions to the second-order nonlinearity of gold. The results provide direct evidence of bulk contributions, nevertheless, surface-like contributions dominate the measured signals.
