Abstract
We have built an automated and computer driven experimental set-up allowing systematic determinations of the built up and the temporal behaviour of the phase conjugate optical wave produced by a self-pumped phase conjugate mirror (SPPCM) using photorefractive crystals. Experiments have been carried out on two different barium titanate (BaTiO 3) samples to obtain experimentally the influence of temperature and the geometrical parameters on the reflectivity of the mirror, its time constant and stability. The dependence of the phase conjugate wave (PCW) intensity on position and incident angle of the incident input beam is discussed on the basis of the MacDonald-Feinberg model in which we assume a distribution of fanning.
