Abstract

Surface second-harmonic generation excited by photorefractive surface electromagnetic wave with a diffusion mechanism of nonlinearity has been observed at the surface of the negative $c$ axis of a ${Sr}_{0.6} {Ba}_{0.4} {NbO}_{3}$ (SBN:60) experimentally. The second-harmonic $532 nm$ wavelength light is generated by $1064 nm$ laser in a passive guiding manner in the experiment, for the wavelength of the fundamental beam is insensitive to the SBN crystal. The transfer efficiency of surface second-harmonic generation is 1%/W.
