Abstract

A new subharmonic regime in photorefractive bismuth silicon oxide has been discovered by the use of the running-grating technique. In this regime the subharmonic grating splits into two gratings that are angularly tilted with respect to the fundamental grating. These observations necessitate an extension of previously proposed theories.
