P. Provencher et al., SURFACE 2ND-HARMONIC SUSCEPTIBILITY DETERMINED BY NONCOLLINEAR REFLECTED 2ND-HARMONIC GENERATION, Canadian journal of physics, 71(1-2), 1993, pp. 66-69
We investigate the noncollinear reflected second-harmonic generation (
SHG) for monolayers of Rhodamine 6G adsorbed on fused silica. We show
that the ratios between the surface molecular chi(2) components can be
related to the values of the polarization angles of the two incident
beams when minima of the resulting SHG intensity are obtained.
