Second harmonic generation from the Cu(001) surface
Surface Science 352-354, pp 684-688 (1996)
We report on measurements of the second harmonic (SH) yield from a Cu(001) surface in the wavelength range between 740 nm and 840 nm which is below the one photon excitation threshold of d-electrons. The SH-yield varies strongly with the azimuthal angle of the Cu crystal indicating a significant contribution of bulk anisotropic SH generation.
