Abstract
Consistent experimental and numerical simulation studies of photorefractive surface wave propagation in Bi12TiO20 and Bi12SiO20 crystals are presented. We induce the photorefractive surface wave with a Gaussian beam of small diameter and show that light leakage from the surface wave takes the form of multiple beam reflection from the crystal surface. The efficiency of surface wave excitation is proved to be much higher for the divergent Gaussian beam than for the convergent one.
