Abstract
The influence of beam coupling on photorefractive parametric oscillati on generated in a Bi12SiO20 crystal is investigated experimentally by comparing two configurations with and without the presence of beam cou pling. It is shown that beam coupling has a great influence; for examp le, the transversal split of the K/2 subharmonic grating is seen only in the beam-coupling geometry. A case that resembles K/4 subharmonic g eneration can, however, still be found in the absence of beam coupling . (C) 1998 Optical Society of America.
