Abstract
The intensity of the second-harmonic light generated in reflection from piezoelectric crystals of GaAs has been measured as a function of the angle of incidence of the primary ruby- or neodymium-glass-laser beam. The second-harmonic intensity has been measured for various crystallographic orientations of the GaAs mirror surface and for different directions of polarization. The results verify the theoretical predictions of Bloembergen and Pershan. In particular, the existence of a "Brewster angle" for second-harmonic reflection, with the harmonic electric field in the plane of reflection, has been observed.Keywords
