Abstract
We have performed experiments to establish the origin of phase defects in a phase-conjugate cavity composed of a curved mirror of high refle ctivity and a phase-conjugating mirror based on four-wave mixing in ph otorefractive BaTiO3 pumped by counterpropagating Ar+ laser beams. An intracavity diaphragm was used to change the Fresnel number, thus prov iding the observation of different transverse structures in the output plane of the photorefractive oscillator.
