We demonstrate how the phenomenological constants usually used to describe the nonlinear surface and bulk polarization associated with optical second-harmonic generation from cubic [(100) crystal face] and isotropic centrosymmetric metals can be determined by combining the results of experiments in which the p-polarized second-harmonic intensity is determined as a function of (i) the angle of incidence, (ii) the (linear) polarization direction of the fundamental beam, and for single crystals (iii) the orientation of the crystal. Experimental results for polycrystalline Cu and Al and for single-crystalline Al with a (100) face are reported. Experimental results for hexagonal single-crystalline Zn giving the intensity of the p-polarized second-harmonic generation as a function of (i) the state of polarization of the incident light and (ii) the rotational angle of the crystal, which has the c axis in the surface plane, are presented.
