摘要：

We report observation of strongly enhanced surface second harmonic generation (SHG) in BaTiO3 due to excitation of a photorefractive surface electromagnetic wave. Surface SH intensity may reach 10(-2) of the incident fundamental light intensity. Angular, crystal orientation, and polarization dependencies of this SHG are presented. Possible applications of this effect in nonlinear surface spectroscopy are discussed.
