Webmodels to describe SHG were proposed [7-11]. In particular, the simplified bond-hyperpolarizability model (SBHM) applied to Si crystal surfaces is ve ry interesting because the physical mechanism of SHG is stated clearly in classical terms and only requires a few free parameters to model the data obtained by experiment [9, 10].
