Abstract
Incoherent-to-coherent conversion by use of the photorefractive beam-fannin g effect and amplification by two-wave coupling have been demonstrated expe rimentally in a photorefractive Ba1-xSrxTiO3 crystal. The converted coheren t image is amplified by 60x. The resolution of the amplified coherent image is similar to 28 line pairs/mm. A notable advantage of the method is that incoherent-to-coherent conversion and coherence amplification of the conver ted coherent image are realized simultaneously in a photorefractive crystal .
